FUNCTIONAL DESCRIPTION

Operational Capabilities

The FRE-765 List 4x RT enclosure requires the following plug-in units:

•

one RT Line Unit which is line powered via the HDSL pairs that connect the RT to the PG-Flex COT line
units installed in a COT Shelf.

•

one Channel Unit, minimum, with a maximum installation of three Channel Units, supporting up to 24
channels.

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 24-channel system, you can provision a maximum of 24 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).
