Introduction

T1/FT1 OVERVIEW

T1 digital communication links have been used by telcos for the
transmission of voicesince 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 O fferings

T1 is a digital service that is 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 exten ded superframe
(ESF), is available. ESF provides a non-disruptive means of full­time monitoring on the digital facility. It was originally used by
service providers to monitor the performanceof their service

Chapter 1. Introduction

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 equipm ent (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. See Figure 1-1.

Figure 1-1. T1 ESF CSU ACE Application

1-2 T1 ESF CSU ACE User Manual 61203025L1-1

Chapter 1. Introduction

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 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.

Features

Chapter 1. Introduction

Figure 1-3. Jack Signal Directions

The fol low ing features give the T1 ESF CSU ACE many advantages
over other products of its kind:

• Smallest T1 ESF CSU ACE in the industry.

• Front panel interface eliminates the need for a terminal to
configure the T1 ESF CSU ACE.

• Automatic ESF to D4 frame conversion

• Wall mount -48 VDC power supply e liminates the need for an
external power supply.

• Power cable enables customers to use their own -48 VDC
supply.

• Can be wall mounted to virtually any surface. There are rubber
feetontheunitforuseonatabletop.

• Can configure a modem so that it does not have to be
configured before installation.

• Backs up configuration data in NVRAM and EEPROM so that
the configuration data is nonvolatile longer than the life of the
lithium battery in the NVRAM. The NVRAM holds
performance monitoring data as well.

• Automatic network interface line build out (LBO) eliminates
confusion over transmit LBO setting (dependent on distance
from last repeater to customer premises).

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>

<CONTROL-P> <CONTROL-T> <CONTROL-T>

The terminal or terminalemulation software must be VT-100 compatible.

T1 ESF CSU ACE TESTING

The T1 ESF CSU ACE offers three forms of testing:

or

•Selftest

•Loopbacktests

• Pattern generation

Self Test

The self test checks the integrity of the internal operation of the
electronic components by performing memory tests and by sending
and verifying data test patterns through all internal interfaces.
Although actual user data cannot be pas sed 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
commanded 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

1-8 T1 ESF CSU ACE User Manual 61203025L1-1

operation to confirm continued correct functioning. The
background tests include the standard background network
performance monitoring as required by ANSI T1.403 andAT&T
54016, for which the results are stored.

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-of­band 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 Figure 1-4.

• Line Loopback - Loops all of the received data back toward the

• Payload Loopback - Similar to line loopback, except that the

network. The transmitted data is the identical line code that
was received, including any bipolar violations or framing
errors.

framing is extracted from the received data and then
regenerated for the transmitted data.

Figure 1-4. Network LoopbackTests

61203025L1-1 T1 ESF CSU ACE User Manual 1-9

Chapter 1. Introduction

DTE Interface Loopbacks

Loops all data from the terminal interface (T1) 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.
SeeFigure1-5.

Figure 1-5. DTE Interface Loopback

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

TheAllZerospatternsendszerosinallthepayloadbitsandis
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.

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 device's protocol-specific
frames inside a frame rely frame. The networkaccepts only frames formatted
specifically for frame relay; therefore interface devices acting 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 destination device, it
receives de-encapsulated data (i.e., the frame relay frame is stripped off, leaving
only the user's data) from the interface device.

FCS

frame check sequence. The standard 16-bit cyclic redundancy check used for
HDLC an d 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.

FDL

facility data link. A 4 kbit/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.

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
