System Hardware Manual
If set for T1, the T1/PRI blade provides 24 trunks in a single universal
slot. These trunks can be one of the following:
Loop Start
Ground Start
DID
E&M Trunks
ANI/DNIS E&M Trunks
T1 provides the system the advantage of advanced digital trunking
and conserving universal slots. For example, a system with 12 loop
start trunks, two tie lines and six DID trunks would use up to five
universal slots. With T1, all these trunks are available in a single
universal slot. This frees up four additional universal slots for other
uses.
If set for PRI, each T1/PRI blade provides 24 PRI (23 B & 1 D)
channels running at 1.544Mbps with 64Kb/s clear channel. This
blade supports the following PRI services:
Basic PRI Call Control (BCC)
Display of incoming caller's name and number (when allowed by the
telco)
Speech and 3.1 KHz audio
When installed, CD-PRTA uses the first block of 24 consecutive
trunk ports. For example, if a COIU blade is installed for trunks 1~8,
the CD-PRTA automatically uses trunks 9~32. If the COIU blades
are installed for trunks 1~8 and 17~24, CD-PRTA uses trunks
25~48. The CD-PRTA cannot use trunks 9~16 (even if available)
since they are not part of a consecutive block of 24 trunks. Each
CD-PRTA requires 24 ports in the system, even if not all the ports
are used, otherwise the blade does not function.
The CD-PRTA requires one universal slot and provides:
1.5M or T1 Function
