If set for PRI, each PRI/T1/E1 blade provides 32 PRI (30 B & 2 D)
channels running at 2.048Mbps 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 30 consecutive trunk
ports. For example, if a CD-4COTA(with PZ-4COTE) blade is
installed for trunks 1~8, the CD-PRTA automatically uses trunks
9~40. If the CD-4COTA(with PZ-4COTE) blades are installed for
trunks 1~8 and 17~24, CD-PRTA uses trunks 25~56. The CD-PRTA
cannot use trunks 9~16 (even if available) since they are not part of a
consecutive block of 32 trunks. Each CD-PRTA requires 32 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.
Refer to the following table for maximum upgrade capacities of the
CD-PRTA blade:
