[2] = Loop Start Disconnect supervision is not supported for Loop Start 
emulation of T-1 circuits.
[3] = Ground Start Software supports disconnect supervision for ground start 
emulation of T-1 circuits.
[4] = DID The DID signaling (wink, delay, and immediate) is controlled in 
Flash 45. DID digits from the carrier are routed via the DID 
table. To program the DID table, refer to Flash 44 
programming on 
page 2-108 and to Flash 43 programming 
on page 2-113.
[5] = TIE This is used for point-to-point T-1 applications.

in Flash 45. DNIS digits from the carrier are routed via the DID 
table. To program the DID table, refer to Flash 44 
programming on 
page 2-108 and to Flash 43 programming 
on page 2-113.
[7] = TIE/ANI The ANI number is treated and routed as an ICLID number. It 
follows the Flash 43 programming (

Description
The T-1 Ringback option supports T-1 channels which require ringback tone to be 
transmitted to the caller while a call is ringing. Some carriers require the system to generate 
the ringback tone, this feature allows the system to provide this option. Ringback tone is not 
used with the DISA, TIE Line, or DID signal options.

T-1 Collect Timer
Description
The T-1 Collect Timer is only used when the T-1 Incoming Signaling is set for dial pulse. This is 
a time-out timer that looks at the incoming digits one digit at a time.
If a second digit isn’t detected within the 150ms, the telephone system attempts to process 
that digit. If a second digit is detected, the system waits 150ms to see if a third digit is 
received. Otherwise, the telephone system attempts to process the two digits already 
received. This process continues until no additional digits are received and the time-out 
timer expires.
The T-1 Collect Timer setting is variable from 100ms to 2.0 seconds.
Programming Steps
1. Press the T-1 COLLECT TIMER flexible button (FLASH 40, Page C, Button #10). The 
following message is shown on the display phone:
2. Enter a valid number on the dial pad which corresponds to 010–200 (100 ms to 
2.0 seconds).
3. Press the HOLD button to save the entry. A confirmation tone sounds and the display 
updates.

T-1/ISDN Alarm Programming
Description
The T-1 Trunk card and the system software provide tools to help detect and isolate problems 
which may occur with the T-1 circuit. There are six LEDs mounted on the outside edge of the 
T-1 Trunk card which either light or flash to indicate a variety of conditions on the T-1 circuit. 
The Central Office Maintenance Center can send a command to place the CSU into Line Loop 
Back mode. If there is no CSU, the T-1 Trunk card responds to the Line Loop Back command.
The buttons on the digital telephone are defined as shown below when entering the T-1 
Alarm programming area:
Programming Steps
If the system is in the programming mode, continue using the program codes. If starting to 
program here, enter the programming mode.
1. Press FLASH and dial [47]. The following message displays:
2. Press a button (1-7) that represents the desired alarm setting.

These settings govern all T-1 Trunk cards installed in the system.

The LED lights steady when the button is pressed.

Once the desired alarm is selected, the following conditions can be programmed:
Button #12 = Clears the alarm
Button #13 = Minor threshold setting
Button #14 = Major threshold setting
Button #15 = Time period for Minor/Major alarms

Attendant Station
Enable/Disable (Carrier Loss Alarm)
Description
A Receive Carrier Loss (RCL) condition is declared when no bits have been received by the T-1 
Trunk card for 150ms. It causes an Out of Frame (OOF) condition, and 2.5 seconds later a RED 
Carrier Failure Alarm (CFA) state. During the time the RCL and RED alarm are declared, 
incoming and outgoing signal bits are frozen. Outgoing calls cannot be made.
Programming Steps
1. Press the CARRIER LOSS flexible button (FLASH 47, Button #1). Button #1 and Button 
#11 LEDs are lit steady. The following message displays:
2. Enter a 0 or 1 on the dial pad to enable/disable this feature.
[0] = Disabled
[1] = Enabled
3. Press the HOLD button to save the entry. A confirmation tone sounds and the display 
updates.
DEFAULT … Carrier Loss Alarm is enabled on all T-1 trunks.
Blue Alarm
Description
The Blue Alarm signal is an unframed all ones signal. It is transmitted by a remote device 
(usually a CSU) and when received, indicates a transmission failure upstream of that device 
toward the local end. The AIS alarm signal is also known as the keep alive signal in that it 
prevents the T-1 circuit repeaters from malfunctioning when transmit from the remote end is 
lost.
Programming Steps
1. Press the BLUE ALARM flexible button (FLASH 47, Button #2). Button #2 and Button #11 
LEDs are lit steady. The following message displays:
2. Enter a 0 or 1 on the dial pad to enable/disable this feature.

Yellow Alarm
Description
The Yellow Alarm is recorded when the T-1 Trunk card detects a yellow Carrier Failure Alarm 
(CFA) signal from the distant end for a minimum 335 ms. The Yellow Alarm is transmitted by 
the remote system because of a RED alarm condition there.
Programming Steps
1. Press the YELLOW flexible button (FLASH 47, Button #3). Button #3 and Button #11 LEDs 
are lit steady. The following message displays:
2. Enter a 0 or 1 on the dial pad to enable/disable this feature.

3. Press HOLD button to save entry. A confirmation tone sounds and the display updates.
4. Continue programming the Yellow Alarm parameters using steps provided in this section 
for Clearing the alarm, Minor alarm, Major alarm, Time Period and Attendant display.
DEFAULT … Yellow Alarm is enabled for all T-1 Trunks.
Red Alarm
Description
The Red Alarm is declared by the T-1 Trunk card when a loss of signal is detected, or an Alarm 
Indication Signal is received. A Red Alarm can be caused by a loss of carrier signal, a receive 
out of frame sync condition, or an alarm indication signal.
Programming Steps
1. Press the RED ALARM flexible button (FLASH 47, Button #4). Button #4 and Button #11 
LEDs are lit steady. The following message displays:
