Introduction
GENERAL DESCRIPTION
The ADTRAN T1 Data Service Unit (TSU), in either the standalone o r
the rackmount (RM) version for the Smart 1 6 shelf, provides a reliable,
high-speed data connection from customer synchronous data terminal equipment (DTE) through T1/FT1 lines.
The TSU serves as the link between user data sources such as LAN
bridges and routers, computers, CAD systems, and teleconferencing
equipment. The amount of bandwidth allocated to the port is userprogrammable at Nx56 or Nx64 kbps wher e N = 1 to 24. The DTE data
can occupy contiguous or alternate channels in the T1 stream and the
channels may start at any position. The DTE port provides a V.35 electrical and physical interface.
The network interface may be either D4 superframe format (SF) or extended superframe format (ESF) and the line code may be straight

The user configures and controls the TSU through the controller card
in the SMART 16 shelf. The user has two choices of input/output devices for the controller card.
• An EIA-232 port, mounted on the rear of the shelf, provides a
VT 100 compatible ASCII terminal interface. A modem can be
used for remote applications.
• The ADTRAN DATAMATE, an optional hand-held control unit,
provides a 2x16-character LCD display and an 18-position keypad.
However, if the controller is a Smart16e, a 1 0BaseT interface is provided for Ethernet connection. In this way the unit may be configured and
controlled via a MIB browser, or via Advision.

Chapter 4. Operation
Network Options
Format
This option selects the framing format for the network interface. Superframe format (SF) and extended superframe format (ESF) are the
two choices. ESF provides an out-of-band communications channel
that allows the carrier to retrieve performance monitoring data and
initiate loopbacks in accordance with ANSI T1.403 and AT&T 54016.
If on a public network, this setting must be in accordance with the type
of service provided by the carrier.
Line Code
This option selects whether the TSU uses straight AMI line coding or
B8ZS. B8ZS ensures
placing an all
0s
-density requirements on the network by re-
1s
byte with a specific byte containing two intentional
bipolar violations (BPVs). If on a public network, this setting must be
in accordance with the service provided by the carrier.
Yellow Alarm
This option enables or disables the transmission of yellow alarms by
the TSU. When the TSU is in red alarm caused by loss of signal/out
of frame conditions (LOS/OOF), a pattern may be sent towards the
network to alert the carrier/far end of the red alarm. In D4 format, the
yellow alarm is sent in-band and thus corrupts the data in the outgoing direction. Some private network applications may require that the
yellow alarm transmission be disabled. If using a carrier-provided T1,
enable the yellow alarm.
Transmit Performance Report Message (XMIT PRM)
When this option is enabled, a status update (Performance Report
Message) is sent towards the network by the TSU when in ESF m ode.
This report is sent in accordance with ANSI T1.403 and is a summary
of the last four seconds of operation. Enable this option unless told
otherwise by the carrier. The PRM is sent when this option is
61202077L1-20 TSU RM with V.35 User Manual 4-5
ON
.
Chapter 4. Operation
Clock Source
A master timing source must be defined for proper operation of the T1
link. If the TSU is connected to a carrier-provided T1 line, the clock
source should be set to
work, the user must option one of the TSUs for
the other to internal or

. If the TSU is part of a private net-
NETWORK TIMING
. When optioned for
INTERNAL
and
tioned for DTE, the TSU derives timing from the DTE transmit clock.
Bit Stuffing
Bit stuffing is an option used to ensure pulse density requirements on
carrier-provided T1 lines in accordance with ANSI T1. 403 and AT&T
62411. If B8ZS is e nabled, Nx56 is optioned, alternat e channels are being used, or inverted data (HDLC) is used, the N pulse density requirement is already met and bit stuffing should be disabled. If none
of the above options are selected, enable bit stuffing.
Bit stuffing corrupts the user data from the DTE when it fails
to meet the 12.5 perce n t 1s de n sity re qu ireme n t. If the DTE
data do not meet this requ irement , enab le one o f the ab ove options.
Set Line Build Out
Set Line Build Out (Set LBO) selects the transmit level of the outgoing
T1 stream. Attenuation of the T1 signal can be added to avoid overdriving repeaters on the T1 line. On most carrier-provided T1 lines, a
smart jack is installed at the network demarcation point and should
receive a
signal. If there is no smart jack, the auto line build-out
0 dB
feature may be deployed. This feature enables the TSU to base its
transmit level on the level of the signal received from the network. If
trouble exists with the auto line build-out feature, try each of the selections until achieving reliable operation.

RX Sensitivity
This option selects the desired receiver sensitivity setting. The factory
default is
EXTENDED
NORMAL
NORMAL
, which is adequate for most applications. The
setting should be used only in applications where the
setting will not suffice.
DTE/Other Options
Rate (Nx56/64)
This selection chooses whether the DTE data rate is Nx56 or Nx64
kbps, where N = 1 to 24. N corresponds to the number of channels occupied within the T1/FT1 stream.
On Fractional T1 (FT1), the user is billed based on bandwidth (number
of channels allocated) so N determines the cost of a circuit. On a private network, the li miti ng f actor fo r N wi ll be the max imum da ta ra te
of the DTE equipment.
On a carrier-provided T1 that does not support B8ZS, Nx56 may be
chosen to ensure pulse density requirements and eliminate 1s density
restrictions on the DTE data. The trade -off is a 1/8 red uction in bandwidth.
The alternate channels option discussed below may also be used to
meet this requirement; however, the carrier must allow it. The maximum number of channels is 12.
Contiguous/Alternate Channels
As mentioned above, the TSU may be optioned to use contiguous or
alternate channels within the T1 stream. The
AL TERNATE CHANNELS
option provides another means of meeting pulse density requirements. If the number of channels is no more than 12 and the carrier
allows this setting, this option may be the better solution.
The
ALTERNATE CHANNELS
option means that every other channel
within the T1 (from the starting channel position through the ending
channel position) is occupied with DTE data. All other channels wi ll
have idle code.
61202077L1-20 TSU RM with V.35 User Manual 4-7
Chapter 4. Operation
The
Contiguous Channels
option means that the DTE data occupy one
channel after the other (starting at the programmed channel and using
the number of channels chosen).
DTE Transmit (Tx) Clock
This option controls the clock the TSU uses to accept the transmit (TX)
data from the DTE. Most applications will allow for this to be set to

settings. If the DTE provides a clock with TX
EXTERNAL
. The TSU will depend on
an externally supplied clock to accept the TX data.
Starting Channel
The DTE data can occupy the T1 stream starting in a ny of the 24 channels. For a full T1 link, this value should be one. For a public FT1 link,
this value should correspond to the value specified by the carrier.
Number of Channels (N)
The number of channels used within the T1 stream can be set from 1
to 24. The user bandwidth and D TE data rate a re determined by Nx56
kbps or Nx64 kbps, depending upon the rate setting described in
Rate (Nx56/64) on page 4-7.
Data Option
The data option may be set for
NORMAL
INVERT
or
. The
INVERT
mode provides another method to meet pulse density requirements.
INVERT
In the
mode, data transmitted to or received from the DTE are

NORMAL
mode.
CTS Option
This option allows Clear To Send (CTS) to operate no rmally (Normal)

DSR is OFF if any of the following conditions exist:
• TSU is in self-test mode.
• TSU is in local loopback mode
• TSU is sending test pattern.
Inband Option
The Inband Configuration Channel ena bles/disables an 8 kbps remote configuration channel. When this option is set to ON, the first
occupied DS0 operates in 56K mode and the DTE clock rate is reduced
by 8 kbps. The TSU uses this 8 kbps channel to send and receive configuration data across a T1 span. This feature is useful when FDL connectivity is not available across the T1 span.
The 8 kbps channel is onl y ta ken o ut of t he first DS0. If t wo 64K D S0s
are mapped, the DTE rate would be 120 kbps instead of 128 kbps. This
menu option can also be set to
AUTO
, which activates the Inband
Channel only when commands are sent from T-Watch to the remote
unit. If no T-Watch activity is detected for 10 minutes, the Inband
Channel is deactivated.

Remote Unit
Remote Loopbacks
When a remote loopback is chosen, a code is sent towards the network
that is intended to loopback the far end TSU. These loopbacks will be
either line (LLB) or payload (PLB) as described in
on page 4-15. Some of these codes are sent out-of-band in the ESF Facility Data Link (FDL - 4 kbps control channel) and some a re se nt inband. The FDL codes only work when the framing bits are actually
transported from one end of the T1 to the other. This type of test is valid for full T1 but may not be for FT1. The AT&T inband LLB and the
V.54 inband PLB do not use the FDL, but the AT&T cod e requires a full
T1 link. For FT1, it is more reliable to use the V.54 INBAND PLB when
the units on both ends support it.

Test Patterns
The TSU can send five different data patterns to the network. These
patterns are used for testing the T1 link. The all 1’s pattern sends all
1s in every channel of the T1. The all 0’s pattern sends all zeros in every channel of the T1. The 1 in 8 pattern sends a fixed pattern where
one out of every eight bits is set. This pattern is used to test pulse density requirements, and also occupies all channels of the T1. The 511
and QRSS patterns are pseudo-random patterns sent only in the active
DS0s.
When a pattern is started from the terminal, a
TSU REST RESULTS
