Introduction  
T1/FT1 OVERVIEW  
T1 digital communication links have been used by telcos for the transmission of voice since the early  
sixties. The D4 channel bank is an example of a T1 digital carrier system that was introduced in the mid-  
seventies and is still widely used by the telcos. Communication demands of business continued to grow to  
the point that the telcos began offering T1 service directly to the public. D4 channel banks were used for  
T1 in corporate network topographies for voice. The technological advances in computer development also  
created a demand for T1 data communication, which now is a large part of the T1 traffic.  
T1 SERVICE OFFERINGS  
T1 is a digital service delivered to the user over two pairs of wires from the service provider. The signal  
operates at 1.544 Mbps and is usually extended by repeaters installed approximately every mile after the  
first 6000 feet. The T1 signal is divided into 24 time slots which operate at 64 kbps (DS0s). Each time slot  
is occupied by digitized voice or by data.  
The T1 signal originally used a type of framing known as D4 superframe (SF), which identifies how the T1  
is multiplexed. An enhancement of that framing format, called extended superframe (ESF), is available.  
ESF provides a non-disruptive means of full-time monitoring on the digital facility. It was originally used  
by service providers to monitor the performance of their service offering. Since the introduction of ESF,  
equipment installed in private networks can also provide this performance information to the user.  
T1 ESF CSU ACE OVERVIEW  
Most carriers (regional or local telcos), when supplying a T1 line to customer premises equipment (CPE),  
require an interface to monitor the T1 line. The T1 ESF CSU ACE (extended superframe channel service  
unit advanced communication equipment) provides the required interface between the CPE (such as DSUs,  
channel banks, T1 multiplexers, and PBXs) and telco or private T1 facilities. Figure 1-1 depicts a typical  
application.

Figure 1-1. T1 ESF CSU ACE Application  
The T1 ESF CSU ACE provides surge protection, signal regeneration, alarms, and loopbacks necessary for  
circuit operation and fault isolation. The unit provides the simultaneous use of performance report  
messages of ANSI T1.403 and maintenance messages of AT&T TR54016. The T1 ESF CSU ACE also  
provides conversion from SF to ESF framing formats, allowing older SF data terminal equipment (DTE) to  
take advantage of the superior diagnostic capabilities of ESF T1 facilities.  
The unit complies with Part 68 of FCC Rules and with applicable sections of AT&T 62411, ANSI T1.102,  
and T1.403.

Chapter 1. Introduction  
FOUR METHODS OF CONTROL  
Front Panel  
The front panel provides complete and easy control of all items that can be configured through  
menu-guided options. The front panel LCD displays the status of operation and performance reports for the  
unit. Chapter 3 contains information on front panel operation and all the menu options.  
ADTRAN PC Program  
T-Watch is the ADTRAN PC control program. It provides complete control over the configuration of the  
T1 ESF CSU ACE through a graphic interface. The T-Watch program displays the same status and  
performance data as the front panel LCD. This data is displayed in the form of tables and graphs.  
The T-Watch program has the following capabilities:  
Interface with modem permits dialing into a remote T1 ESF CSU ACE location to configure the unit or  
read the unit’s status or performance.  
Performance data read from the units can be exported in a file which is compatible with common  
spreadsheet programs.  
SNMP  
The ADTRAN T1 ESF CSU ACE supports the Simple Network Management Protocol (SNMP) through  
the ADTRAN Advisor SNMP Proxy Agent (1950007L1) to a network management system such as  
OpenView® or SunNet Manager™. The proxy agent runs on a PC and can interface to the T1 ESF CSU  
ACE directly or through a modem, in the same manner as the T-Watch PC programs.  
ASCII Terminal  
The ADTRAN T1 ESF CSU ACE recognizes an escape sequence that puts the unit into the ASCII terminal  
mode. After receiving the sequence, the T1 ESF CSU ACE sends front panel information to the terminal.  
This interface acts exactly like the front panel, but the advantage is that it can be accessed remotely  
(through a modem). The escape sequence is:  
<CONTROL-A> <CONTROL-P> <CONTROL-T>  
or  
<CONTROL-P> <CONTROL-T> <CONTROL-T>  
The terminal or terminal emulation software must be VT100 compatible.

Chapter 1. Introduction  
T1 ESF CSU ACE User Manual  
T1 ESF CSU ACE TESTING  
The T1 ESF CSU ACE offers three forms of testing:  
Self test  
Loopback tests  
Pattern generation  
Self Test  
The self test checks the integrity of the electronic components’ internal operation by performing memory  
tests and sending and verifying data test patterns through all internal interfaces. Although actual user data  
cannot be passed during these tests, the self test can be run with the network and DTE interfaces in place  
and will not disturb any external interface.  
The self test automatically executes upon power-up. It can also be initiated from a front panel menu or  
from the control port.  
In addition to the specified self tests, background tests are run on various parts of the internal electronics.  
These run during normal operation to confirm continued correct functioning. The background tests include  
the standard background network performance monitoring as required by ANSI T1.403 and AT&T 54016,  
for which the results are stored.

T1 ESF CSU ACE User Manual  
Chapter 1. Introduction  
Loopback Tests  
A number of different loopbacks can be invoked locally from the front panel, by T-Watch commands, or  
remotely by using special inband codes (AT&T network loop-up and loop-down codes). Additionally, the  
loopbacks can be remotely controlled by out-of-band commands using the T1 ESF FDL, or from T-Watch  
using a modem connection. A discussion of network loopbacks and DTE interface loopbacks follows.  
Network Loopbacks  
There are two types of network loopbacks: line loopbacks and payload loopbacks. These are illustrated in  
Line Loopback - Loops all of the received data back toward the network. The transmitted data is the  
identical line code that was received, including any bipolar violations or framing errors.  
Payload Loopback - Similar to line loopback, except that the framing is extracted from the received data  
and then regenerated for the transmitted data.  
Figure 1-5. Network Loopback Tests  
DTE Interface Loopbacks  
Loops all data from the terminal interface (TI) back towards the T1. This loopback may be initiated using  
front panel, EIA-232 control port, or T-Watch commands. The DTE (or external test equipment) must  
provide any test pattern in order to check the DTE interface. See Figure 1-6.

Chapter 1. Introduction  
T1 ESF CSU ACE User Manual  
Pattern Generation  
The T1 ESF CSU ACE offers three test patterns: All Ones, All Zeros, and 1:8. These patterns can be  
initiated from the front panel, through the EIA-232 control port, or remotely via a management software  
like T-Watch.  
All Ones  
The All Ones pattern sends ones in all the payload bits.  
All Zeroes  
The All Zeros pattern sends zeros in all the payload bits and is useful for testing line code configuration  
(AMI/B8ZS mismatches).  
1 in 8 (1:8)  
Each channel of the T1 has only one bit set. This pattern is used in conjunction with external test  
equipment to determine whether the T1 line is performing acceptably under a stress condition.  
APPLICATIONS  
Three applications are shown in this section. Figure 1-7 on page 27 shows a general data application;  
Figure 1-8 on page 28 shows a general voice application; and Figure 1-9 on page 28 shows a channel bank  
application.

To use the cable of the supplied power supply with a local supply, connect the black wire to the negative pole of  
the power supply and connect the black and white wire to the positive pole of the power supply. The outside  
contact point of the barrel plug connects to the negative pole and the center contact point of the barrel plug  
connects to the positive pole.  
WIRING  
The connectors are described in this section.  
RJ-48C Connectors  
Two RJ-48C connectors are located on the back end of the T1 ESF CSU ACE. The NET connector  
connects the unit to the network. The connector marked CPE connects the unit to the data terminal  
equipment. These connectors have exactly the same pinouts.  
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.  
See Table A-1 on page 51 for the RJ-48 connector pin assignments.  
EIA-232 Connector  
The EIA-232 connector is used to connect the T1 ESF CSU ACE to a proxy agent, T-Watch, an ASCII  
terminal, or a modem.  
See Table A-2 on page 51 for the connector pin assignments.

POWER-UP TESTING AND INITIALIZATION  
When shipped from the factory, the T1 ESF CSU ACE is set to factory default conditions. When power is  
applied, the unit automatically executes self test, followed by an initialization sequence that sets up the  
unit.  
Self Test  
Upon a power-up or self test, the LCD displays ADTRAN T1 ESF CSU ACE INITIALIZING and the  
LEDs illuminate momentarily. When the self test is completed with no failures detected, the LCD  
momentarily displays ALL TESTS PASSED. If a failure is detected, it is displayed in the LCD window.  
The automatic self test procedure consists of the following steps:  
1. Board level tests - RAM tests; EPROM checksum  
2. Unit level tests - Front panel LED verification

GENERAL FRONT PANEL MENU OPERATION  
The T1 ESF CSU ACE uses a multilevel menu structure containing both menu items and data fields. All  
menu operations and data are displayed in the LCD window. The menu items are numbered and can be  
viewed by using the scroll keys (the arrow keys on the front panel).  
Description of Menu Tools  
Data Field  
A menu item followed by a colon (:) identifies a field available for editing.  
Display Field  
This menu field contains alarm or error information.  
Arrows  
Menus that display small up or down arrows in the lower right corner indicate that there are more menu  
items viewable on the two-line LCD. Access additional menu items with the up or down scroll keys.  
Example Menu Operation  
Selecting a Main Menu Item  
To select a menu item from the Main menu, follow these steps:  
1. Use the up and down scroll keys to place the cursor on the desired menu item (in this example,  
2)CONFIG). See Figure 3-2.  
Figure 3-2. Selecting a menu item from the Main Menu  
2. With the cursor on the number 2), press the ENTER key. The unit responds by displaying the first two  
available submenu fields. The cursor is on the first field. If there are more than two menu fields, a down  
arrow is visible on the lower right corner. See Figure 3-3.

Selecting a Submenu Item  
To select the desired submenu item (similar to selecting a Main menu item), follow these steps:  
1. Use the up and down scroll keys to place the cursor on the desired menu item, in this example  
1)NETWORK (NI). See Figure 3-3.  
2. The unit responds by displaying the first two available data field items. The cursor is on the number of  
the first item. When there are more than two data field items for the selected submenu, a down arrow  
is visible on the lower right corner. See Figure 3-4.  
Figure 3-4. Submenu Indicating Additional Items Not Shown  
Setting/Cancelling the Data Field  
Data fields available for editing are preceded by a colon (:). To set a data field, perform the following steps:  
1. Press ENTER while the cursor is located on the submenu item number. The cursor moves to the data  
field (to the right of the submenu item name). See Figure 3-5.  
Figure 3-5. Editing a Data Field  
2. Use the up and down scroll keys to scan the available value settings displayed one at a time in the  
data field position.  
3. When the desired value is in the data field position, press ENTER to set the value. The unit now is set  
for the value shown in the data field and the cursor moves back to the submenu item position,  
indicating that the operation is complete. Another submenu field may be selected, or use CANCEL to  
return to the submenu.  
Cancelling is available any time during the operation. If CANCEL is used prior to  
pressing ENTER after making a data change, the original data value is restored and the  
cursor returns to the submenu field.

Chapter 3. Operation  
Tests are used to control the activation of loopbacks, the initiation of data test patterns, and self test  
execution.  
1)LOCAL LOOPBK, Submenu of 4)TEST  
Four choices are available for setting the local loopback:  
NO LOOPBACK Deactivates the loopback  
DTE ON  
LINE ON  
PAYLOAD ON  
Activates the DTE loopback  
Activates the line loopback  
Activates the payload loopback  
Figure 3-20. Local Loopback Test Screen  
2)REM LB, Submenu of 4)TEST  
Activates the same loopbacks as the LOCAL LOOPBCK but at the far end. This uses either the inband  
loop-up code as specified by AT&T 62411 for line loopback (ATT In-Band LLB), or the FDL as  
specified in ANSI T1.403 for line loopback codes. An FDL (formerly TABS) maintenance message  
corresponding to AT&T TR54016 can be used for payload loopback as well:  
NO LOOPBACK  
Deactivates the loopback.  
AT&T INBAND LLB Activates the line loopback using inband code.  
ANSI FDL LLB  
AT&T FDL PLB  
Initiates the transmission of an FDL line loop-up code toward the far end.  
Initiates the transmission of the PLB maintenance messages on the FDL.  
When a loopback method is selected, the T1 ESF CSU ACE displays LOOPING in the top  
right corner of the LCD and the yellow LOOPBACK LED is turned on. When the T1 ESF  
CSU ACE determines that the far-end T1 ESF CSU ACE has looped up, the T1 ESF CSU  
ACE displays LOOPED. If the T1 ESF CSU ACE does not recognize the remote T1 ESF  
CSU ACE looped up after about 10 seconds, the T1 ESF CSU ACE sends the appropriate  
loop-down code and displays FAILED, and the LOOPBACK LED is turned off.  
Excessive errors on the T1 line can cause this failure. The FDL loopbacks fail if the FDL  
is not intact from one end point to the other. FDL loopbacks are valid only in the ESF  
framing mode.

erate a 1:8 test pattern and inserts the  
pattern into all DS0s.  
Select  
To end the test.  
NO PATTERN  
4)RUN SELFTEST, Submenu of 4)TEST  
Use this menu selection to execute an internal self test. This is the same self test that is performed  
automatically at power-up. The results of the self tests are displayed in the LCD (see Figure 3-21).  
Upon invoking the command, the LCD displays INITIALIZING and test failures are displayed in the  
LCD window.  
Figure 3-21. Self Test Result Screen  
If a failure is detected, note the failure prior to contacting ADTRAN technical support.  
The execution of a self test disrupts normal data flow and prevents remote communication  
until the self test is completed (approximately five seconds).

4-wire Switched 56  
An AT&T proprietary 56/64 kbps switched digital data service offered by telco service providers and delivered  
to users over 4 copper wires. Compatible with the T1 ESF CSU ACE 4-wire Switched 56 DBU option.  
ANSI  
American National Standards Institute. Devices and proposes recommendations for international communica-  
tions standards.  
asynchronous  
A method of data transmission which allows characters to be sent at irregular intervals by preceding each char-  
acter with a start bit, followed by a stop bit.  
bandwidth  
The bandwidth determines the rate at which information can be sent through a channel (the greater the band-  
width, the more information that can be sent in a given amount of time).  
BECN  
backward explicit congestion notification. A bit set by a frame relay network to notify an interface device  
(DTE) that congestion avoidance procedures should be initiated by the sending device.  
bridge  
A device that supports LAN-to-LAN communications. Bridges may be equipped to provide frame relay support  
to the LAN devices they serve. A frame relay capable bridge encapsulates LAN frames in frame relay frames  
and feeds them to a frame relay switch for transmission across the network. A frame relay capable bridge also  
receives frame relay frames from the network, strips the frame relay frame off each LAN frame, and passes the  
LAN frame on to the end device. Bridges are generally used to connect LAN segments to other LAN segments  
or to a WAN. They route traffic on the Level 2 LAN protocol (e.g. the Media Access Control address), which  
occupies the lower sub-layer of the LAN OSI data link layer. See also router.  
CCITT  
Consultive Committee for International Telephony and Telegraphy. A standards organization that devises and  
proposes recommendations for international communications. See also ANSI.  
CD  
carrier detect. A signal generated by a modem or DSU/CSU. CD indicates the presence of a carrier signal on a  
communications link.  
clocking  
An oscillator-generated signal that provides a timing reference for a transmission link. A clock provides signals  
used in a transmission system to control the timing of certain functions. The clock has two functions, (1) to gen-  
erate periodic signals for synchronization and (2) to provide a time base.  
CPE  
customer premise equipment. All telecommunications terminal equipment located on the customer premises,  
including telephone sets, private branch exchanges (PBXs), data terminals, and customer-owned coin-operated  
telephones.

Appendix D. Glossary  
T1 ESF CSU ACE  
CRC  
cyclic redundancy check. A computational means to ensure the accuracy of frames transmitted between devices  
in a frame relay network. The mathematical function is computed, before the frame is transmitted, at the origi-  
nating device. Its numerical value is computed based on the content of the frame. This value is compared with a  
recomputed value of the function at the destination device. See also FCS.  
CS  
See CTS.  
CSU  
channel service unit. A device used to connect a digital phone line (T1 or Switched 56 line) coming in from the  
phone company to either a multiplexer, channel bank, or directly to another device producing a digital signal;  
for example, a digital PBX, a PC, or data communications device. A CSU performs certain line-conditioning  
and equalization functions, and responds to loopback commands sent from the central office. A CSU regener-  
ates digital signals. It monitors them for problems, and provides a way of testing the digital circuit.  
CTS  
dB  
clear to send. A signal on the DTE interface indicating that the DCE is clear to send data.  
decibel. A unit of measure of signal strength, usually the relation between a transmitted signal and a standard  
signal source.  
DCE  
DDS  
data communications equipment. Device that provides all the functions required for connection to telephone  
company lines and for converting signals between telephone lines and DTE. Also see DTE.  
digital data service. A private line digital service, for transmitting data end-to-end at speeds of 2.4, 4.8, 9.6, and  
56 kbps and in some cases 19.2, 38.4, or 64 kbps. The systems can use central hub offices for obtaining test  
access, bridging legs of multipoint circuits, and cross connecting equipment. DDS is offered on an inter-LATA  
basis by AT&T and on an intra-LATA basis by the Bell operating companies.  
DE  
discard eligibility. A user-set bit indicating that a frame may be discarded in preference to other frames if con-  
gestion occurs, to maintain the committed quality of service within the network. Frames with the DE bit set are  
considered excess data.  
DLCI  
data link connection identifier. A unique number assigned to a PVC end point in a frame relay network. Identi-  
fies a particular PVC endpoint within a users access channel in a frame relay network and has local signifi-  
cance only to that channel.  
DSU  
data service unit. A device designed to transmit and receive digital data on digital transmission facilities.  
DSU loopback  
A telco initiated test which loops the DSU back to the telco and is used to test the DDS circuit as well as the  
DSU/CSU.

Appendix D. Glossary  
DTE  
data terminal equipment. The end-user terminal or computer that plugs into the termination point (DCE) of a  
communications circuit. The main difference between the DCE and the DTE is that pins two and three are  
reversed.  
encapsulation  
A process by which an interface device places an end devices protocol-specific frames inside a frame rely  
frame. The network accepts only frames formatted specifically for frame relay; therefore interface devices act-  
ing as interfaces to a frame relay network must perform encapsulation. See also interface device or frame relay  
capable interface device.  
end device  
The ultimate source or destination of data flowing through a frame relay network sometimes referred to as  
DTE. As a source device, it sends data to an interface device for encapsulation in a frame relay frame. As a des-  
tination device, it receives de-encapsulated data (i.e., the frame relay frame is stripped off, leaving only the  
users data) from the interface device.  
FCS  
FDL  
frame check sequence. The standard 16-bit cyclic redundancy check used for HDLC and frame relay frames.  
The FCS detects bit errors occurring in the bits of the frame between the opening flag and the FCS, and is only  
effective in detecting errors in frames no larger than 4096 octets. See also CRC.  
facility data link. A 4 bit/s non-disruptive management channel provided in ESF framing mode. This data link  
conforms to ANSI T1.403 and AT&T TR 54016 specifications.  
FECN  
forward explicit congestion notification. A bit set by a frame relay network to notify an interface device (DTE)  
that congestion avoidance procedures should be initiated by the receiving device. See also BECN.  
file server  
In the context of frame relay network supporting LAN-to-LAN communications, a device connecting a series  
of workstations within a given LAN. The device performs error recover and flow control functions as well as  
end-to-end acknowledgment of data during data transfer, thereby significantly reducing overhead within the  
frame relay network.  
frame-relay-capable interface device  
A communications device that performs encapsulation. Frame-relay-capable routers and bridges are examples  
of interface devices used to interface the customers equipment to frame relay network. See also interface  
device and encapsulation.  
frame relay frame  
A variable-length unit of data, in frame-relay format that is transmitted through a frame relay network as pure  
data. Contrast with packet. See also Q.922A.  
frame relay network  
A telecommunications network based on frame relay technology. Data is multiplexed. Contrast with packet  
switching network.

nization for Standardization (ISO). HDLC manages synchronous code-transparent, serial information transfer  
over a link connection. See also SDLC.  
hop  
A single trunk line between two switches in a frame relay network. An established PVC consists of a certain  
number of hops, spanning the distance form the ingress access interface to the egress access interface within the  
network.  
host computer  
The primary or controlling computer in a multiple computer operation.  
in-band  
Signaling (dialing, diagnostics, management, configuration, etc.) over the same channel used for data.  
ingress  
Frame relay frames leaving from an access device in a direction toward the frame relay network.  
interface device  
Provides the interface between the end device(s) and a frame relay network by encapsulating the users native  
protocol in frame relay frames and sending the frames across the frame relay backbone. See also encapsulation  
and frame-relay-capable interface device.  
ISDN  
Integrated Services Digital Network. A network architecture that enables end-to-end digital connections. The  
network supports diverse services through integrated access arrangements and defines a limited set of standard,  
multipurpose interfaces for equipment vendors, network providers, and customers. Networking with a public  
switched telephone network is retained.  
LAN  
local area network. A privately owned network that offers high-speed communications channels to connect  
information processing equipment in a limited geographic area.  
out-of-band  
Signaling that is separated from the channel carrying information (voice, data, video, etc.). Typically the sepa-  
ration is accomplished by a filter. The signaling includes dialing and other supervisory signals.  
packet  
A message containing both control information and data. The control information is used for routing the packet  
through a network to its final destination. Contrast with frame relay frame.  
packet-switching network  
A telecommunications network based on packet-switching technology, wherein a transmission channel is occu-  
pied only for the duration of the transmission of the packet. Contrast with frame relay network.  
parameter

ping  
An internet protocol standard that provides loopback on demand for any device in an IP network. One device  
“pings” another by sending a loopback request to the device's IP address.  
point-to-point  
Type of communications link that connects a single device to another single device, such as a remote terminal  
to a host computer.  
PVC  
permanent virtual circuit. A frame relay logical link, whose endpoints and class of service are defined by net-  
work management. Analogous to an X.25 permanent virtual circuit, a PVC consists of the originating frame  
relay network element address, originating data link control identifier, terminating frame relay network element  
address, and termination data link control identifier. Originating refers to the access interface form which the  
PVC is initiated. Terminating refers to the access interface at which the PVC stops. Many data network custom-  
ers require a PVC between two points. Data terminating equipment with a need form continuous communion  
use PVCs. See also DLCI.  
remote configuration  
A feature designed into ADTRAN DSU/CSU products that allow remote DSU/CSU to be configured from a  
local DSU/CSU or VT100 compatible terminal.  
router  
A device that supports LAN-to-LAN communications. Routers may be equipped to provide frame relay support  
to the LAN devices they serve. A frame-relay-capable router encapsulates LAN frames in a frame relay frames  
and feeds those frame relay frames to a frame relay switch for transmission across the network. A frame-relay-  
capable router also receives frame relay frames from the network, strips the frame relay frame off each frame to  
produce the original LAN frame, and passes the LAN frame on to the end device. Routers connect multiple  
LAN segments to each other or to a WAN. Routers route traffic on the Level 3 LAN protocol (e.g., the internet  
protocol address). See also bridge.
