ABOUT THE PRODUCT
1
The ADC Campus-RS™ (Rate-Selectable) Fractional Interface Card provides
a connection between a High-bit-rate Digital Subscriber Line (HDSL) and a
network or other digital equipment. It installs into either a:
•
Campus-Star chassis, along with a Campus-RS Line Unit
•
Campus-RS Desktop Unit
This equipment comprises half of a High-bit-rate Digital Subscriber Line
(HDSL) transmission system. When connected to another Campus-RS,
Campus-T1®, Campus-768®, or Campus-E1® Desktop Unit or Line Unit, the
Campus-RS system can transport digitized voice, data, and video signals over
existing copper wire at a number of different HDSL rates.
The Campus-RS Fractional Interface Card converts incoming data, control
signals, and timing information into its internal format. The desktop unit or
line unit then converts this format to a Two Bit, One Quaternary (2B1Q)
HDSL line format for high-speed transmission over a local telephone-grade
copper network.

About the Product
COMPATIBILITY WITH EARLIER CAMPUS
PRODUCTS
Campus-RS Fractional Interface Card Compatibility
When mated with a Campus-RS Desktop Unit or Campus-RS Line Unit (see
“Campus-RS Desktop and Line Unit Compatibility”), the Campus-RS
Fractional Interface Card is compatible, over the HDSL link, with earlier
versions of Campus products, such as the Campus-T1, Campus-E1, and
Campus-768, as shown in the following illustration.
Campus-T1, Campus-E1
or Campus-768
Campus-RS
Campus-RS
Fractional
Interface card
HDSL
Legacy Campus
Interface card
All earlier versions of Campus products are manufactured to operate at a
single HDSL transmission rate, while the Campus-RS transmission rate is
user-selectable. To support compatibility with the application shown above,
the following configuration options must be set on the Campus-RS Fractional
Interface Card:
•
Set the HDSL Operating Mode to Standard Mode
•
Set the Standard Mode HDSL Rate to T1, E1, or 768, to match the rate
of the earlier product.
For information on setting these options, see “Set the HDSL Operating
Mode” on page 3-2.
Campus-RS Desktop and Line Unit Compatibility
Campus-RS Desktop and Line Units are fully compatible with most of the
earlier versions of Campus products, including Campus-E1®, Campus-T1®,
and Campus-768™. The Campus-RS Desktop and Campus-RS Line Units are
not currently compatible with Campus-384® products.
1-2
Campus-RS Fractional Interface Card User Manual
About the Product
Furthermore, if a Campus-RS unit is connected over an HDSL link to an
earlier Campus product, and if either unit has the HDSL Transceiver (XCVR)
Mode set to AUTO, the HDSL link may not operate properly.
When operating the Campus-RS product with an earlier version of the
Campus products, to avoid any problems with link startup or operation, it is
recommended that the Transceiver Mode be set as follows:
•
Campus-RS = MASTER
•
Campus E1/T1/768 = SLAVE
If one or both units are already set to AUTO and the HDSL link is active,
disconnect the HDSL link, change the settings as recommended, and
reconnect the link. This will assure the link integrity on any subsequent
startups.
This situation does not apply to a circuit with two Campus-RS
units. You may leave the units set to their default setting of
AUTO, and they will operate properly.
Channel Reversal
The current release of Campus-RS does not recognize HDSL loop reversal.
That is, the cable pairs must be “straight through,” with Loop A connected to
pins 1 and 2 of the Line Connector on both ends of the loop, and Loop B
connected to pins 4 and 5.
A possible symptom of loop reversal is to observe the LCD Margin on an RS
unit display during startup. The loop display will alternate between “ACK”
and “SIG” as expected. Then, one loop may display margin values as if the
link is synchronizing, but after 1 to 2 seconds will drop back to startup.
A future firmware release will allow automatic detection and compensation
for loop reversal.

When connecting to another Campus-RS Desktop Unit or Line Unit,
Standard Mode is still supported, providing access to HDSL transmission
rates of T1, E1, and 768 kbps. In addition, the Campus-RS system can be
configured to support an extended set of HDSL transmission rates, over either
one or two HDSL loops.
Not all modes and rates may be available. Some Campus-RS
interface cards support only a limited set of operating modes
and transmission rates. Refer to the remote interface card
user manual to see the HDSL modes and rates supported by
the card.

Campus-RS Fractional Interface Card User Manual
About the Product
To support these additional transmission rates, set the following options on
the Fractional Interface Card:
•
Set the HDSL Operating Mode to Extended Mode.
•
Set the Extended Mode Loop Configuration to 1 Loop or 2 Loops,
depending on the physical layout of your HDSL network.
•
Set the Extended Mode HDSL Rate to the desired setting. The range of
rates available for the HDSL Rate depends on the setting of the Extended
Mode Loop Configuration:
–
1 Loop HDSL Rate settings are between 64 kbps and 2.304 Mbps,
in 64 kbps increments
–
2 Loop HDSL Rate settings are between 256 kbps and 4.608 Mbps,
in 128 kbps increments
For the 2 Loop HDSL configuration, specific revisions of
the Fractional Interface Cards only support a top rate of
2.304 Mbps configuration. Contact ADC for additional
information regarding the affected part numbers.
For information on setting these options, see “Set the HDSL Operating
Mode” on page 3-2.

Some options, such as the HDSL Rate must be the same for
both the local and remote unit. Resetting the Campus unit
configuration values on one unit only, may cause the HDSL
link to go down.
SETTING THE DATA RATE
The HDSL Mode setting determines the data rate. Depending on the mode
you want to set, continue with either “Standard Mode Data Rates” or
“Extended Mode Data Rates.”
Standard Mode Data Rates
In Standard HDSL Mode, the HDSL line always operates at a constant rate,
however the Fractional Interface Card can be set to operate synchronously at
integer multiples of either 56 kbps or 64 kbps (n x 56 kbps or n x 64 kbps). In
addition, the Fractional Interface Card can also be configured to operate at
“full rate,” where all the user bandwidth of the HDSL line is made available
to the data port.

INVERTING THE TRANSMIT CLOCK
There may be circumstances in which it is either desirable or necessary to
invert one or more of the TT, SCT, and SCR clocks. This could be true if the
host equipment provides inverted clock signals, if the differential clock
signals are switched in the data cable, or if there is excessive clock delay. The
Fractional Interface Card allows you to invert any of these clock signals by
changing the appropriate Invert Clock option.
For physical-layer protocols which have unbalanced (single-ended) clock
signals, the Invert Clock option has the effect of simply inverting the clock
signal. This appears as a 180° phase delay. For physical-layer protocols
which have balanced (two-wire) clock signals, the Invert Clock option has the
effect of switching the inverting and non-inverting contacts.
There are two settings for each Invert Clock option:
•
OFF leaves the output clock in its normal, non-inverted, state.
•
ON inverts the clock signal or, for the TT input, inverts the input signal
internally.
To invert a transmit clock:

1
Press Escape until CAMPUS RS I/F: FRAC displays.

INVERTING DATA SIGNALS
The Fractional Interface Card allows you to invert the SD and RD signals.
Some protocols, such as X.25, use this data inversion to satisfy the ones
density requirement of T1 lines operating in AMI mode. Unless specifically
required by a protocol, do not use data inversion.
There are two settings for the Data Inversion option:
•
OFF leaves SD and RD signals in their normal, non-inverted, state.
•
ON inverts the SD and RD signals.

CONFIGURING OUTPUT CONTROL SIGNALS
The fractional interface cards provide four standard output control signals:
•
RLSD (Receive Line Signal Detect)
•
TM (Test Mode)
•
DSR (Data Set Ready)
•
CTS (Clear to Send)
The operation of each control signal depends upon the specific operating
mode selected. Each control signal can be individually configured for one of
three modes:
4-12
•
ON forces the control signal to remain on permanently, regardless of any
other control signal activity or changes in unit status.
•
OFF forces the control signal to remain off permanently, regardless of
any other control signal activity or changes in unit status.
•
STD sets to signal according to the standard rules for control signal
operation found in RS-449 and RS-530 interfaces, as described below:
–
RLSD is on as long as the HDSL link is synchronized. If the HDSL
link is not synchronized, then RLSD is off.
–
TM is on whenever a loopback function is active at either the local
or remote unit. The TM signal is affected by both V.54 loopbacks
and loopbacks that are initiated through the LCD or terminal menus.
Campus-RS Fractional Interface Card User Manual
Configuring and Monitoring Through the LCD
–
DSR follows the state of the Data Terminal Ready (DTR) input
signal. When the DTR input is turned on, the DSR output is turned
on. When the DTR input is turned off, the DSR output is turned off.
This type of operation is consistent with standard operation for
non-switched communications equipment operating on a dedicated
private channel, such as HDSL.
–
CTS follows the state of the Request to Send (RTS) input signal.
When the RTS input is turned on, the CTS output is turned on. When
the RTS input is turned off, the CTS output is turned off. This type
of operation is consistent with standard operation for non-switched
communications equipment operating on a dedicated private
channel, such as HDSL.
To configure the control signal options to the desired settings:
1
Press Escape until CAMPUS RS I/F: FRAC displays.

CONFIGURING AS A MASTER OR SLAVE UNIT
The Transceiver Mode option determines the hierarchy of the two Campus
units when attempting to establish an HDSL link. There are three settings:
•
If a unit is set to Master, it initiates the HDSL link. The other Campus
unit must be set to Slave or Auto.
•
If a unit is set to Slave, it waits for the other Campus unit to initiate the
HDSL link. The other unit must be set to Master or Auto.
•
If a unit is set to Auto, it automatically switches between Master and
Slave until an HDSL link is established. The setting of the other Campus
unit is irrelevant. This is the default setting.
Unless you have a compelling reason for doing otherwise,
ADC recommends leaving the Transceiver Mode option set to
Auto.

Campus-RS Fractional Interface Card User Manual
Configuring with an ASCII Terminal
Setting the Primary Timing Source
The primary timing source determines the timing for the entire HDSL system.
Timing can come from one of three parts of the Campus system:
•
Data Port receives timing through the host equipment connected to the
data port.
•
Internal receives timing from the internal oscillator of the Campus unit
(default setting).
•
HDSL receives timing over the HDSL line.
Either the local or remote unit must have the timing source set to HDSL. The
other unit must be set to Data Port or Internal, depending on the system setup.
See “Timing Source” on page 8-1 for examples of timing configurations.
To set the Primary Timing Source:
1
From the Data Port Settings menu, type 3 then press ENTER . The
Timing Source option changes to the next available setting.
2
Repeat the previous step until the Data Port Settings menu displays the
desired Timing Source setting.
Setting the Transmit Clock
The Transmit Clock option determines how the SD signal is sampled if the
Timing Source is set to Internal or HDSL. There are two settings:
•
External SD is sampled based on the clock transitions on the TT input.
•
Internal SD is sampled based on the clock transitions on the SCT output.
For complete information about the Transmit Clock option, see “Transmit
Clock” on page 8-4.
To set the Transmit Clock:
1
From the Data Port Settings menu, type 4 then press ENTER . The
Transmit Clock option changes to the next available setting.
2
Repeat the previous step until the Data Port Settings menu displays the
desired Transmit Clock setting.
Campus-RS Fractional Interface Card User Manual

Configuring with an ASCII Terminal
Inverting the Transmit Clock
There may be circumstances in which it is either desirable or necessary to
invert one or more of the TT, SCT, and SCR clocks. This could be true if the
host equipment provides inverted clock signals, if the differential clock
signals are switched in the data cable, or if there is excessive clock delay. The
Fractional Interface Card allows you to invert any of these clock signals by
changing the appropriate Invert Clock option.
For physical-layer protocols that have unbalanced (single-ended) clock
signals, the Invert Clock option has the effect of simply inverting the clock
signal. This appears as a 180° phase delay. For physical-layer protocols
which have balanced (two-wire) clock signals, the Invert Clock option has the
effect of switching the inverting and non-inverting contacts.
There are two settings for each Invert Clock option:
•
OFF leaves the output clock in its normal, non-inverted, state.
•
ON inverts the clock signal or, for the TT input, inverts the input signal
internally.
To invert the input clock (TT):
1
From the Data Port Settings menu, type 5 then press ENTER . The Invert
Input Clock option changes to the next available setting.
2
Repeat the previous step until the Data Port Settings menu displays the
desired invert clock setting.
To invert the output transmit clock (SCT):
1
From the Data Port Settings menu, type 6 then press ENTER . The Invert
Output TX Clock option changes to the next available setting.
2
Repeat the previous step until the Data Port Settings menu displays the
desired invert clock setting.
To invert the output receive clock (SCR):

1
From the Data Port Settings menu, type 7 then press ENTER . The Invert

Inverting Data Signals
The Fractional Interface Card allows you to invert the SD and RD signals.
Some protocols, such as X.25, use this data inversion to satisfy the ones
density requirement of T1 lines operating in AMI mode. Unless specifically
required by a protocol, do not use data inversion.
There are two settings for the Data Inversion option:
•
OFF leaves SD and RD signals in their normal, non-inverted, state.
•
ON inverts the SD and RD signals.
To invert the SD and RD signals:

Repeat the previous step until the Data Port Settings menu displays the

Configuring Output Control Signals
The fractional interface cards provide four standard output control signals:
•
RLSD (Receive Line Signal Detect)
•
TM (Test Mode)
•
DSR (Data Set Ready)
•
CTS (Clear to Send)
The operation of each control signal depends upon the specific operating
mode selected. Each control signal can be individually configured for one of
three modes:
•
ON forces the control signal to remain on permanently, regardless of any
other control signal activity or changes in unit status.
•
OFF forces the control signal to remain off permanently, regardless of
any other control signal activity or changes in unit status.
Campus-RS Fractional Interface Card User Manual
5-19
Configuring with an ASCII Terminal
•
STD sets to signal according to the standard rules for control signal
operation found in RS-449 and RS-530 interfaces, depending on the
signal:
–
RLSD is on as long as the HDSL link is synchronized. If the HDSL
link is not synchronized, then RLSD is off.
–
TM is on whenever a loopback function is active at either the local
or remote unit. The TM signal is affected by both V.54 loopbacks
and loopbacks that are initiated through the LCD or terminal menus.

DSR follows the state of the Data Terminal Ready (DTR) input
signal. When the DTR input is turned on, the DSR output is turned
on. When the DTR input is turned off, the DSR output is turned off.
This type of operation is consistent with standard operation for
non-switched communications equipment operating on a dedicated
private channel, such as HDSL.
–
CTS follows the state of the Request to Send (RTS) input signal.
When the RTS input is turned on, the CTS output is turned on. When
the RTS input is turned off, the CTS output is turned off. This type
of operation is consistent with standard operation for non-switched
communications equipment operating on a dedicated private
channel, such as HDSL.
To configure the control signal options to the desired settings:

CONFIGURING AS A MASTER OR SLAVE UNIT
The Transceiver Mode option determines the hierarchy of the two Campus
units when attempting to establish an HDSL link. There are three settings:
•
If a unit is set to Master, it initiates the HDSL link. The other Campus
unit must be set to Slave or Auto.
•
If a unit is set to Slave, it waits for the other Campus unit to initiate the
HDSL link. The other unit must be set to Master or Auto.
•
If a unit is set to Auto, it automatically switches between Master and
Slave until an HDSL link is established. The setting of the other Campus
unit is irrelevant. This is the default setting.
Unless you have a compelling reason for doing otherwise,
ADC recommends leaving the Transceiver Mode option set to
Auto.

TESTING THE SYSTEM
7
The Fractional Interface Card supports a complete set of loopback functions
that allow you to test the data communication path between the host
equipment, the Campus unit, and the remote unit. You can use the LCD and
menu buttons or an ASCII terminal to initiate loopback tests.
To initiate a loopback from the LCD, see “Configuring Loopbacks” on
page 4-20. To use an ASCII terminal to initiate a loopback, see “Configuring
Loopbacks” on page 5-28.
Initiating a loopback test interrupts normal system operation and the TEST
LED on the desktop unit or line unit front panel flashes. When the loopback
is cancelled, the system returns to normal operation automatically.
TYPES OF LOOPBACKS
There are four loopback tests you can use with the Fractional Interface Card.
Each tests a different portion of the communication path, which lets you
isolate communication problems. For each test, the terms “local” and
“remote” are relative to the Campus unit from which you initiate the loopback
test. The Fractional Interface Card supports the following loopback tests:
•
Local to Local Interface
•
Remote to Local Interface
•
Remote to Remote Interface
•
Local to Remote Interface

Testing the System
Remote to Local Interface
The Remote to Local loopback tests the local data port, the entire data path
inside the local Campus unit, the HDSL line, the HDSL transceivers of both
units, and most of the internal data path inside the remote unit.
Use this loopback to verify that the HDSL line is operational, and that the
HDSL transceiver of the remote unit is operational. This loopback also tests
the same areas as the Local to Local and Local HDSL loopbacks. The remote
host equipment is not involved in this type of loopback.
Remote to Remote Interface
The Remote to Remote loopback tests the remote data port and a small
portion of the remote Fractional Interface Card.
Use this loopback to verify that the remote host equipment, remote data cable,
and remote interface card are installed and configured properly. The local
host equipment is not involved in this type of loopback.
Local to Remote Interface
The Local to Remote loopback tests the remote data port, the entire data path
inside the remote Campus unit, the HDSL line, the HDSL transceivers of both
units, and most of the internal data path inside the local unit. This loopback
does not test the local data port drivers and receivers.
Use this loopback to verify data communication from the remote host device
to the internal data paths of the local Fractional Interface Card. The local host
equipment is not involved in this type of loopback.

CANCELLING LOOPBACKS
There are two ways to cancel a loopback test:
•
cancel the loopback manually
•
set the Loopback Timeout option to cancel the loopback after a set period
of time
Cancelling Loopbacks Manually
You can cancel a loopback from either the LCD or an ASCII terminal. To use
the LCD, see “Configuring Loopbacks” on page 4-20. See “Configuring
Loopbacks” on page 5-28 to use an ASCII terminal.
Loopback Timeout
When using a loopback, there is a possibility that it will be forgotten. If this
happens, the communication link remains down. To prevent this from
happening, you can set the Loopback Timeout configuration option. There
are four different settings for this option:
•
None
•
20 Minutes
•
60 Minutes
•
120 Minutes
This option determines how long a loopback remains active. When the
Loopback Timeout option is set to one of the above values, the loopback is
cancelled and normal communication is resumed after the set time has
elapsed. If you set this option to None, the loopback remains in effect until
you cancel it manually.
To set the Loopback Timeout through the LCD, see “Setting the Loopback
Timeout” on page 4-21. To use an ASCII terminal, refer to “Setting the
Loopback Timeout” on page 5-30.

V.54 Loopback Support
The Fractional Interface Card supports V.54-compliant loopbacks, which
enable initiation of loopback tests from a V.54-capable host device. Before
you can use V.54 loopbacks, you must enable V.54 loopback support. To
enable V.54 loopback support through the LCD menu, see “Enabling V.54
Loopback Support” on page 4-22. See “Enabling V.54 Loopback Support” on
page 5-31 to enable V.54 loopback support through an ASCII terminal.
The V.54 support function is implemented through the following control
signals on the data port:
•
LL Signal (input): When the LL (local loopback) input is activated by
the host device, the Fractional Interface Card initiates a Local to Local
loopback as described on page 7-2. The Fractional Interface Card also
turns on the TM output signal to provide confirmation of the loopback.
The TM signal and Local to Local loopback remain active until the LL
signal is turned off.
•
RL Signal (input): When the RL (remote loopback) input is activated
by the host device, the Fractional Interface Card initiates a Remote to
Local loopback as described on page 7-3. The Fractional Interface Card
also turns on the TM output signal to provide confirmation of the
loopback. The TM signal and Remote to Local loopback remain active
until the RL signal is turned off.
•
TM Signal (output): The TM (test mode) signal is activated by the
Fractional Interface Card in response to activation of an LL or RL signal.
The TM signal is also activated when any other loopback is initiated from
the LCD, ASCII terminal, or V.54 control signals from the remote unit.
The TM signal indicates to the local host device that a loopback test is
active, regardless of how the test was initiated.
During normal operation, when no loopback is active, all three signals are off.
When a V.54 loopback is in effect, the LL and RL input signals cannot be on
at the same time. For example, when the RL signal is active, the LL signal is
ignored.

TIMING AND
CLOCK OVERVIEW
8
This chapter describes different issues in determining the correct settings for
Campus-RS Fractional Interface Card clock and timing source options.
TIMING SOURCE
For normal operation, communications networks normally require that
communicating elements be separated into data circuit-terminating
equipment (DCE) and data terminal equipment (DTE). DCEs normally
provide timing information for the DTEs.
Campus-RS Fractional Interface Cards can operate in two basic network
timing configurations:
•
Standard timing configuration: The local and remote Fractional
Interface Cards are both connected to DTE hosts.
•
Port timing configuration: One of the Fractional Interface Cards
(either the local or the remote) is connected to a DTE host, and the other
is connected to a DCE host.
The Fractional Interface Cards are currently not capable of operating in a
configuration where both hosts are DCE, and both Fractional Interface Cards
are configured for port timing.
Campus-RS Fractional Interface Card User Manual

Timing and Clock Overview
Standard Timing Configuration
In this configuration, the internal oscillator of one unit is used as a frequency
reference for all clocks in the system. Since the Fractional Interface Cards are
designed as DCE, they are expected to provide both Serial Clock Transmit
(SCT) and Serial Clock Receive (SCR) output signals. Within a Campus
system, set the Timing Source option for one of the Fractional Interface Cards
to HDSL timing, as shown in the following figure. The connected host
devices then use the SCT and SCR timing signals in order to derive transmit
and receive timing for the Send Data (SD) and Receive Data (RD) signals.

The Terminal Timing (TT) signal shown in the figure above compensates for
clock and data delays associated with long cables, or delays that may be
inherent to the connected host equipment. Although it is highly
recommended, the TT signal is optional in this timing configuration. If the TT
signal is used, the host equipment must derive the TT signal from the SCT
signal. This is discussed further in the “Transmit Clock” section of this
manual.
8-2
Campus-RS Fractional Interface Card User Manual
Timing and Clock Overview
Port Timing Configuration
If one of the Fractional Interface Cards needs to accept primary timing from
the connected host equipment, set its Timing Source option to Port timing. Set
the Timing Source option for any connected Campus units to HDSL timing.
The TT input of the “Port-timed” unit is used as a frequency reference for all
clocks in the system, as shown in the figure below. A phase lock loop (PLL)
keeps the Campus system in phase with the host timing. In this configuration,
the TT input of the “Port-timed” unit serves a different purpose than in the
figure on page 8-2, and the Transmit Clock option becomes irrelevant. The
TT input is used as a means of establishing the primary timing reference for
both of the fractional interfaces and the HDSL link. Because the TT input is
used to synchronize all clocks, excessive jitter and poor frequency stability at
the TT input can cause degraded link performance.

The timing configuration shown in the figure above reverses the DTE/DCE
role on one of the Fractional Interface Cards, forcing it to act as DTE instead
of DCE. With this timing configuration, and with a DTE/DCE “cross-over”
cable, you could connect one of the Fractional Interface Cards to a standard
DCE host, as shown in the figure below.

Timing and Clock Overview
The SCT signal on the Fractional Interface Cards cannot be configured as an
input. Also, in a standard DCE host, the SCT signal is also an output. There
are two critical implications for the configuration shown in the figure above:
•
The Fractional Interface Card accepts only one clock input (TT), this
clock is assumed to provide a timing reference for both the transmit and
receive data paths. The Fractional Interface Card uses the TT input to
clock-in the SD input, and to clock-out the RD output. For proper
operation, the DCE host must generate SCT and SCR from the same
primary timing source. SCT and SCR can have a constant phase delay
relative to each other, but they must be generated from the same timing
source.
•
Because the Fractional Interface Card synchronizes the RD output to the
SCR clock output pin, the DCE host must be configured to sample the
SD input based upon the TT clock input.
TRANSMIT CLOCK
Set the Transmit Clock option only if the Timing Source is set to either
Internal or HDSL. When the Timing Source option is set to Port timing, the
Transmit Clock option does not need to be set because TT is equivalent to
SCT. The Transmit Clock option can be set to either External or Internal, and
determines how the SD signal is sampled.
•
External: The SD is sampled based upon the clock transitions on the TT
input.
•
Internal: The SD is sampled based upon the clock transitions on the
SCT output.
One of the functions of the TT signal is to compensate for potential problems
with clock and data delays associated with long cables, or delays that may be
inherent to the connected host equipment. Potential delay problems exist
when the SD signal arriving at the input of the Fractional Interface Card
experiences phase delays relative to the SCT clock provided at the output of
the Fractional Interface Card (shown in the figure below). This occurs when
the data cable causes a significant delay on the SCT and SD signals, or when
the host equipment delays the transmission of the SD signal, relative to the
transitions on the received SCT signal, causing the SCT and SD signals to
lose synchronization.

To circumvent this potential problem, set the Transmit Clock option on the
Fractional Interface Card to External, so that the transmit clock is taken from
the TT input instead of the SCT output. With this approach, the TT and SD
signals experience the same delay as they propagate through the data cable,
and remain synchronized to each other.
When the Timing Source is set to either Internal or HDSL, the SCT signal is
used by the Fractional Interface Card to establish the frequency of the
transmit data path. It does not necessarily indicate exactly where the
transitions on SD should occur. SD typically has a constant phase delay from
SCT. The TT signal, on the other hand, indicates the exact location of the
binary transitions on SD. Any phase delay from the SCT output to the TT
input must be constant. Furthermore, the TT signal cannot be from a different
frequency source than SCT, and should not insert any jitter.
