4.3.5.10 T1 Line Timers – PGM 152
North American T1 standards require that the T1 terminating device, in this case, the iPECS eMG, include
various “adjustable” timers and counters as described below.
COL T1 ATT
ENTER CO RANGE
Press the [PGM] button and dial 152.
01-02 COL T1 ATT
PRESS FLEX KEY (01-13)
Use the dial-pad to enter a CO Line range (Ex. 01-02). For a single CO Line,
enter the same number twice.
Press the desired Flex button; refer to Table 3.3.5.10-1.
Use the dial-pad to enter desired data for the Attribute. Refer to Table
3.3.5.10-1.
Press the [Save] button to store the data entry.
Table 3.3.5.10-1 T1 LINE TIMERS (PGM 152)
01-02 PAUSE
(1-9) : 2 (sec)
A timed pause may be included in a Speed
Dial number, in which case, this entry defines
the pause time. It is not currently
implemented.
01-02 RLS GRD
(01-60) : 20 (100ms)
The release guard timer defines the time the
system will maintain a Line as busy after the
call has been terminated to assure the PSTN
has sufficient time to ‘clear down’ the circuit
and is not currently implemented.
01-02 DT DELAY
(02-50) : 10 (100ms)
The DT (Dial tone) Delay timer defines the
duration of dial tone for DT recognition.
It is not currently implemented.
01-02 INTER DGT
(15-30) : 15 (20ms)
The Inter Digit timer defines the duration
between digit transmissions.
It is not currently implemented.
01-02 WINK
(07-15) : 10 (20ms)
For TIE or DID Lines, the Wink timer defines
the length of time the ‘wink’ (T1 TIE line
circuit reversal) will last.
01-02 OP RATE ( 0- 3)
60-40 (10pps) (0)
For Pulse signaling, defines the duration and
make/break ratio of each pulse.
0: 60-40(10pps), 1: 66-33(10pps)
2: 60-40(20pps), 3: 66-33(20pps)
01-02 SEZ DTC
(000-127) : 003 (20ms)
This timer defines the length of a valid ‘line
seizure’ signal.
