MANUAL VERSION 11.0 – May 2008
T1C, E1/PRI, or T1/E1/PRI Cards Features
4.201 If more than one T1, E1/PRI, or T1/E1/PRI card is installed in the system, the software
uses an ordered list to determine a “back up” to the system reference clock. Then, if the T1,
E1/PRI, or T1/E1/PRI card acting as the system reference clock fails or is taken out of service,
the next T1, E1/PRI, or T1/E1/PRI card on the back-up priority list takes over.
• Error Diagnostics: If desired, the programmer can generate the current T1, E1/PRI, or
T1/E1/PRI error counts (by hour and by day) for the selected card. The error counts are
displayed in tabular format.
• Error Thresholds: The programmer can set numerical thresholds (number per hour
and number per day) for certain T1, E1/PRI, or T1/E1/PRI card errors. If a threshold is
exceeded, an error is printed on the SMDR report.
4.202 The information that is programmed specific to each circuit (e.g., each of the 24 chan-
nels) on the T1 Card includes:
• Circuit Type: Each individual circuit can be programmed as a loop start, ground start,
DID, E&M, or OPX trunk. See PROGRAMMING, page 6-126.
• DTMF or Dial-Pulse Signaling: When the system is in the default configuration, all
trunk circuits are configured for DTMF signaling. If necessary, some or all of the cir-
cuits can be reprogrammed for dial-pulse signaling.
4.203 The T1, E1/PRI, and T1/E1/PRI circuits are assigned hardware address numbers
according to the card’s slot in the equipment chassis and the location of the circuit on the card.
For example, T1 circuit 6.1.21 is the 21st circuit on the 6th card, a T1C, installed in the equip-
ment chassis.
