1213-T1/E1 Card Setup
Description
Use this program to set up the parameters of the T1/E1 PCBs.
Options
1213-01: Number of PCM Channels
(# PCM Channels)
Use this option to determine the number of active channels on the PCB. PCBs configured for T1 have 24 avail-
able channels, while E1 has 30. Enter the number of channels to be active, or enter 0 to activate all channels.
If you are using all channels in the T1, leave this entry at 0. If you are connected to a fractional telco T1 cir-
cuit (e.g., providing only 8 circuits), set this option to match the number of circuit\
s in your fractional span. 
Additionally, you may have to limit the number of active channels if the system has a unique con figuration 
that could exceed the 119 allowable timeslots.
This option always selects the lowest channels. For example, an entry of 8 uses channels 1-8. When connecting 
to a DSU and splitting voice and data channels, the voice channels must be the lower-numbered channels.

1213-02: Clock Control
(Clock Control)
Use this option to specify the clock source for the T1 PCB. The clock is required to synchronize the PCB’s 
operations. The PCB can be either the clock master (1) or the clock slave (2). As master
, the T1 PCB uses its 
own internal clock as the clock source. As sla
ve, the T1 PCB uses the connected T1 circuit from the telco as 
the clock source.
When setting up Tie Lines, keep track of your clock sources. For example, if the local system is the clock 
master, the remote system should be set for slave so it uses the connected circuit as the clock source.

1213-03: Transmit Pulse Amplitude
(Tx Pulse Ampl.)
This option controls the amplitude (strength) of the T1 signals transmitted by the PCB to the telco smart jack 
or your CSU (if used). 
Entries 0-4 correspond to the distance from the T1 PCB to either the telco’s smart jack or your CSU (depend-
ing on your installation). The T1 PCB automatically adjusts the signal amplitude based on your entry.
You can alternately use entries 5-7 to make  fixed attenuation entries. If connected to a CSU, set your attenu-
ation to match the requirements of the CSU. If your T1 PCB is connected directly to the telco’s smart jack, 
the telco will tell you if any attenuation is required.
This option does not apply to E1 circuits.

1213-04: Framer Type
(ESF/CRC4)
Use this option to set the Framer Type used by the PCB. 
If this option is enabled:
❥T1 circuits use ESF (Extended Super Frame) mode. This is a 24-Frame mode which provides ABCD sig- naling bits and additional diagnostics).
❥E1 circuits use CRC-4 16-Frame Multiframe mode.
If this option is disabled:
❥T1 circuits use D3/D4 (12-Frame Multiframe mode which supports AB signaling bits only).
❥E1 circuits do not use CRC4 mode.
Always set this option for compatibility with the connected telco. Normally\
, T1 circuits use ESF. F

(B8ZS/HDB3)
Use this option to enable or disable zero suppression for the PCB transm\
it path. 
If enabled, T1 PCBs use B8ZS zero suppression, while E1 PCBs use HDB3 zero suppressi\
on. 
If disabled, the PCB has no transmit zero suppression. (Note the receive zero suppression is always enabled.)
Zero suppression may help prevent T1 PCB clocking problems, but should always be set for compatibility 
with the connected telco.

None
❥Loopback is not enabled.
Metallic
❥This option loops the T1 PCB internal analog output to the PCB internal analog input. The PCB external  (telco side) connection is isolated during this test.  Metallic Loopback is not normally used as a field test.
Digital
❥This option loops the T1 PCB internal digital output through the PCB’s framer chip and then back to the  PCB internal digital input.  Digital Loopback is not normally used as a  field test .
Remote
❥This option loops any analog signal on the T1 PCB external (telco side) receive tip and ring to the exter- nal (telco side) transmit tip and ring.  Remote Loopback may be useful for field testing because it loops 
any analog test signal on the PCB receive tip and ring back to the transmit tip and ring.

Description
Use this option to customize the system’s number plan. For each dialed digit (0-9, excluding # and *), assign 
a Function Type  and an Expected Digits  entry. Function Type  defines the digit’s function in the system (see 
the table below).
Expected Digits  sets how many digits the system expects to receive when the digit string begins with 
selected digit. For example, digit 3 has  Function Type 2 and Expected Digits  3. This means that digits 300-
399 are Intercom numbers.
