Table 2 shows how circuit assignments are configured in the FRE-765 with the following
deployment rules:
•
For channel units providing four (4) circuits, Ckt 1 through Ckt 4 are used for Tip and Ring
terminations.
•
For channel units providing eight (8) circuits, Ckt 1 through Ckt 8 are used for Tip and Ring
terminations.
•
For a 32-channel system, you can provision a maximum of 32 circuits.
Each PG-Flex channel unit provides four (4) or eight (8) circuits. Table 3 shows how the channels
are assigned, dependent on the type of service provided, such as:
•
Plain Old Telephone Service (POTS)
•
Integrated Services Digital Network (ISDN)
•
Digital Data System (DDS).
