T1/FT1 OVERVIEW
The T1 digital communications link has been used by
telephone companies (telcos) for transmitting voice
since the early sixties. The D4 channel bank is a T1
digital carrier system that was introduced in the mid
seventies and is still widely used by telcos. Communication demands of businesses continued to grow to the
point that the telcos began offering T1 service directly
to the public. D4 channel banks began to be 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.
Chapter 1. Introduction
Chapter 1
Introduction
T1 Service Offerings
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 that are installed about 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 which identifies how the T1 is
multiplexed. An enhancement of that framing format,
called Extended Superframe Format (ESF), is available. It provides a non-disruptive means of full time
monitoring on the digital facility. The ESF was
originally used by the service provider to monitor the

Chapter 1. Introduction
Fractional T1
performance of their service offering. Since the
introduction of ESF, equipment that is installed in
private networks can also provide the same performance information to the user.
Fractional T1 (FT1) lets the buyer purchase less than a
full T1 circuit between two points. Most carriers offer
fractional T1 in increments of 56 or 64 kbps. Connection is made to the same network elements. The
network allows multiple users to share the same
interoffice T1 bandwidth.
Fractional T1 remains almost exclusively an InterExchange Carrier (IXC) service. Local Exchange
Carriers (LECs) typically do not offer FT1, so the
proximity of the user to the point of presence (POP) of
the IXC is key in the savings that fractional T1 offers.
Fractional T1 local access is available in two forms, 56
kbps or a full T1 line. In 56 kbps the required number
of DDS lines is extended from the IXC POP and the
bandwidth is combined at the office on an outbound
T1 circuit. The user pays for the individual 56 kbps
lines and the amount of the interoffice T1 utilized. In
T1 access, the user pays for a full T1 to the IXC POP
and then only for the bandwidth utilized.

Chapter 1. Introduction
The TSU 600 serves as the link between user data
sources such as local area network (LAN) bridges and
routers, computers, CAD systems, teleconferencing
equipment, and PBXs. Through the use of multiple
data ports, the TSU 600 can simultaneously connect
one or more of these devices to a T1 circuit. The
amount of bandwidth allocated to each port is custom
programmable. The bandwidth allocation can be
changed manually or set to automatically change at
predetermined times to use the available bandwidth
most advantageously. Changes in the configuration
are accomplished without disrupting data flow in
channels that are not being reconfigured. The unique
architecture and the availability of the option modules
provides a path for growth to accommodate future
requirements.

OPTION PORTS
The option ports vary depending on the option
modules installed.
Secondary Interfaces (SI)
The secondary interface is an additional interface to a
DS1, a DSX1 facility, or some other network service,
and it offers a source of timing. The type of interface
depends on the option module installed. The interface
includes the following:
• DSX1. Passthru for operation with a PBX (Terminal
Interface - TI).
• Full Drop and Insert. Permits the dropping of data
and insertion of new data into the same DS0 time
slot. This SI module includes a long haul DS1
interface. It can also be used as a second DS1
interface to provide an up to 3 Mbit aggregate
throughput.

TSU 600 CLOCK SOURCES
The TSU 600 is operable from various clock sources
permitting it to perform properly in many different
applications. The network interface clocking options
are set by using the clocking options set by using the
Network (NI) Configuration menu options. The
following clock source options are available:
• Network
• DTE timing
• Internal timing
• Secondary timed
• Normal (CSU)
The clock option selected always designates the clock source
for transmission. Clocking necessary for receiving data is
always recovered from incoming data.
Network Timed
The network is the source of timing. The received data
clocking is looped back to the network where it is used
to determine the transmission timing. This option is
also referred to as loop timed as the transmission clock
is derived from the received clock. See Figure 1-5.

TSU 600 TESTING
The TSU 600 offers three forms of testing:
• Self test
• Loopback tests (local and remote)
• Pattern generation and check
Self Tests
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 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 memory portion of the self test automatically
executes upon power up. A full self test can be commanded from a front panel menu or from T-Watch.
In addition to the specified self tests, background tests
are also run on various parts of the internal electronics. These run during normal operation to confirm
continued correct functioning. The background tests
include: (1) monitoring the phase locked loop for lock,
(2) sending test data through a parallel path which is
looped back and verified, and (3) the standard background network performance monitoring, as required
by ANSI T1.403 and AT&T 54016 specifications for
which the results are stored.
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 in-band codes (AT&T D4
network loop up and loop down codes; V.54 loop up/
loop down codes for the Nx56/64 serial interface).
Additionally, the loopbacks can be remotely controlled
by means of out-of-band commands by the T1 ESF
FDL or from T-Watch by a modem connection.

Chapter 1. Introduction
Classes of Loopbacks
NI CSU
DS1
There are two classes of loopbacks: network interface
and DTE interface.
Network Interface Loopbacks
Network interface loopbacks (see Figure 1-9) affect the
entire T1 data stream. There are two types of network
loopbacks, line loopback and payload loopback.
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 is similar to line loopback, except
that the framing is extracted from the received data
and then regenerated for the transmitted data.
TSU 600
Secondary
Interface
Payload Loopback
Line Loopback
Figure 1-9
Network Loopback Tests
DTE Interface Loopbacks
DTE interface loopbacks affect only that portion of the
data stream programmed to that particular interface
port. The Nx56/64 serial interface offers two loopbacks, a DTE loopback and a port loopback. See
Figures 1-10 and 1-11.
DTE loopback loops all data from the DTE back
towards the DTE. This loopback occurs just past the
interface circuit allowing a verification of the operation of the DTE to TSU 600. This loopback may be
initiated by using front panel or T-Watch commands.
The DTE (or external test equipment) must provide
any test pattern in order to check the DTE interface.
See Figure 1-10.

DTE loopback looping the DTE data back on itself.
The port loopback is activated by command from the
front panel or from the T-Watch program. This causes
a V.54 loopback code to be sent to the far end unit.

Chapter 1. Introduction
Pattern Generation
The TSU 600 offers two available test patterns: QRSS
and 511.
QRSS Pattern
The QRSS pattern is commonly used to simulate real
data in T1 interfaces. This pattern can be assigned to
appear in all DS0s or only in TST DS0s. When QRSS is
set in all DS0s and one of the network loopbacks
previously described is activated at the far end, a total
end-to-end integrity check can be run without the
need for any external test equipment. When QRSS is
assigned to TST DS0s, an integrity check of the link
can be run along with normal data flow. The TST
DS0s are user assigned as part of the DS0 Map.
511 Pattern
The 511 pattern is generated and checked by an
Nx56/64 serial interface option card. It only appears
in the DS0s assigned to the Nx56/64 port which is
generating the pattern. When used in conjunction
with the port loopback at the far end as previously
described, an end-to-end integrity check can be made
on the DTE ports.

POWER UP TESTING AND INITIALIZATION
When shipped from the factory, the TSU 600 is set to
factory default conditions. At the first application of
power, the unit automatically executes a memory self
test. A full self test can be run from the front panel,
and a pass code and unit ID may be set using the UTIL
menu.
Self Test
Upon a power-up, the LCD displays Memory Test
Now Testing and the Test LEDs are illuminated.
When the self test is completed with no failures
detected, the OK LED lights up and the LCD momentarily displays All Tests Passed. If a failure is de-
tected, a list of failures is displayed in the LCD window. The full self test procedure (invoked from the
front panel or T-Watch) consists of the following steps:
1.Board level tests. Each of the TSU 600
boards contains an on board processor
which executes a series of tests checking the
circuitry on the board.
a. RAM tests; EPROM checksum.
b. DS0 map tests.
c. On board data path. Sending a known test
pattern through an on board loop.
Chapter 2. Installation
2.Unit level tests.
a.Front panel LED verification.
b.Phase lock loop verify.
c.Board-to-board interface test. A test pattern is
sent from the controller through a loopback on
all other boards and checked on the controller.
This verifies the data path, clocks, and control
signals.
61200.076L2-1TSU 600 User Manual33
Chapter 2. Installation
Set User Passcode
The TSU 600 is designed to operate with or without
the use of a password.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation
other than viewing.
To Establish a Passcode
Select SET PASSCODE (item 3) under the UTIL menu.
At the New Passcode prompt, use numbers from the
front panel of the keyboard to enter a unique number
up to four (4) digits.
After pressing Enter a verification prompt is displayed. Respond to the verification prompt by
repeating the same passcode number.
If the two entries match, the unit accepts the passcode.
If they do not match the unit returns to the new
passcode entry field for another attempt.
If the unit is to be remotely accessed using T-Watch, a
passcode must be entered. When managing a number of
units, the passcode can be the same for all.
Special Feature
For added security protection the unit is equipped
with an automatic time out for operation with the
password. After ten minutes of inactivity, the unit
reverts to limited access operation. To make changes
in the configuration, the passcode can be reentered.
See Passcode in the chapter Operation for further
information concerning passcode use, and both
limited and editing access.
If the passcode number is lost, contact ADTRAN Customer
Service for assistance.
34TSU 600 User Manual61200.076L2-1
No Passcode Desired
At the New Passcode prompt (in the Set Passcode
menu), press Enter without any numerical entry. The
system nullifies the need to enter a password for
subsequent use and proceeds to the Unit ID prompt.
Set Unit Identification
The Unit ID sets the unit to respond to remote control
(controlled by a device other than the front panel). If
no Unit ID is recorded it is not possible to operate
from any remote control device, including the local
PC.
To Set the Unit Identification
In the Unit ID menu (item 4) under the UTIL menu,
enter any value between 2 and 250. The number 1 is
reserved for the PC.
Pressing Enter records the Unit ID number and
establishes its availability for operation by remote
control. The unit proceeds to the Set Control Port
prompt.

Set Control Port
Control In (PC)
The TSU 600 can be configured from the control port
only when a unit ID number has been entered. (It can
be configured from the faceplate whether a unit ID
number has been entered or not.)
If the control port is to be used, the control port baud
rate must also be selected.
Possible uses of the control port are control in and
chain-in.
The unit can be controlled from an external PC connected directly or via modem to the Control In port.
When using Control In, the selection of the Control
Port baud rate from 9600 (factory default), 1200, 2400,
or 4800 must be made using the Unit Configuration
menu.
Unless locked out externally, the front panel can also
control the unit.
Chain-in
TSU 600s and TSU 100s can be linked together to form
a chain. Figure 2-1 provides an example of a chain-in
arrangement with a PC or a modem. The first TSU 600
in the chain receives controlling input from the PC or
modem.
Subsequent TSUs in the chain are in a position to
intake information from another TSU. This in-taking
of information from another TSU in the chain is
identified as Chain-in. The baud rate for the chained
units must match that of the first unit.
Unless locked out externally, the front panel can also
control the unit.

Network Tests
Operation
Network tests are used to control the activation of
loopbacks and the initiation of data test patterns. See
Figure 3-5 for the list of tests.
Network tests are run on the Network Interface (NI).
Three different test configurations can be selected to
determine the type of loopback and the pattern to run.
Test results are displayed in the LCD window.
The execution of Network Tests will disrupt normal data
flow unless only TST DS0s are selected for testing.
Follow standard operating procedures to access the
Network Tests menu items.
With the cursor on Main menu item 4)TEST, press
Enter or number 4. The unit displays the first two Test
submenu items with the cursor on 1)NETWORK
TESTS. The Down Arrow indicates there are additional menu item selections available.
Press Enter to display the first of three submenu
choices. The cursor is on 1)LOCAL LOOPBCK.
Network Tests Menu Items
The menu items are:
LOCAL LOOPBCK
There are three available choices for setting the local
loopback:
Line On Activates the line loopback
Payload On Activates the payload loopback
No Loopback Deactivates the loopback
Scroll to select a setting and record it by pressing
Enter. The unit returns the display of 1)LOCAL
LOOPBCK and 2)REMOTE LOOPBCK
78TSU 600 User Manual61200.076L2-1
Chapter 3. Operation
REMOTE LOOPBCK
This activates the same loopbacks as Local Loopback
but at the far end. It uses either the inband loop-up
code as specified by ANSI T1.403 for line loopback
(ATT In-Band LLB), or the FDL as specified in ANSI
T1.403 for payload and line loopback codes. The
following options are available:
ATT In-Band LLB Activates the line loopback
using inband code
ANSI FDL PLBInitiates the transmission of
an FDL payload loop-up code
toward the far end
ANSI FDL LLBInitiates the transmission of
an FDL line loop-up code
toward the far end
No LoopbackDeactivates the loopback
Remote Loopback cannot be used with Fractional T1 since
the full T1 stream including the FDL is not transported to
the far end.
After a Remote Loopback option is selected, the
TSU 600 verifies that the far end is actually in a
loopback by checking for the receipt of a code looped
back from the far end. Once the Remote Loopback
type is selected, the LCD displays the loopback
progress by displaying Looping until loopback is
verified.

PATTERN
This sets the pattern for the test and initiates the
transmission of the pattern. The test is terminated by
selecting None. The following patterns are available:
QRSS All DS0sGenerates a QRSS test pattern
and inserts the pattern into all
DS0s
QRSS TST DS0sInserts a QRSS pattern in those
DS0s mapped as TST in the
currently active map (A or B)
NoneTerminates pattern generation
All onesInserts an all ones test pattern
into all DSOs
All zerosInserts an all zeros test
pattern into all DSOs
QRSS always runs at 64K/DS0.
Use the up and down scroll to select, for example,
QRSS ALL DS0. Press Enter to record the selection.
The
TSU 600 starts to generate a QRSS test pattern and
inserts the pattern into all DS0s.
To end the test, select None.
PATTERN RESULT
Displays the results of the test currently active. See
Figure 3-21. Leaving and returning to this menu item
does not interrupt the test.
Code (version K or later): Pressing 2 injects errors into the
test pattern. These errors are detected by the device performing the pattern check.

Results can be cleared by pressing Clear (shift 9).
The results are accumulated until the test pattern is set
to None or Cleared.
The use of TST DS0s for testing can be very useful,
particularly in Fractional T1 applications. An end to end
test can be run on the Fractional DS0s by 1) setting for
Map B the TST in the same DS0 as used by Map A to
receive data from an Nx56/64 port and 2) by looping the far
end using a V.54 loopback code on the Nx56/64 port. In
addition, a single DS0 can be used for continuous testing
while other DS0s are passing normal data. This will also
provide an end to end check on the entire link. Set each end
to send QRSS in TST DS0s (using 1 DS0) and occasionally
view the results on the Pattern Result menu selection.

Run Selftest
This menu selection is used to execute a full internal
self test. The results of the self tests are displayed in
the LCD. Upon invoking the command the LCD
displays System Self-Test and the Test LEDs are
illuminated. Test failures are displayed in the LCD
window. The self test consists of the following steps:
1. Board level tests. Each of the TSU 600 boards
contain an on board processor which executes a
series of tests checking the circuitry on the board.
a. RAM tests; EPROM checksum
b.DS0 map tests
c.On board data path; sending a known test
pattern through an on board loop
2. Unit level tests.
a. Front panel LED verification
b.Phase Lock Loop verify
cBoard to board interface test
A test pattern is sent from the controller
through a loopback on all other boards and
checked on the controller. This verifies the
data path, clocks, and control signals.
If a failure is detected, note the failure number prior to
contacting ADTRAN Technical Support.
The execution of Self Test will disrupt normal data flow and
prevent remote communication until the Self Test is
completed.

VOICE AND DATA MIX
The following is an example of the use of a TSU 600 to
mix voice data from a PBX with data from a
customer’s DTE, possibly a LAN bridge (see Figure 4-
1). This example assumes that B8ZS service is not
available end to end and therefore must use 56K (672K
rate) for the data and run AMI on the network. In
addition, the format on the network is ESF while the
PBX is D4.
