ESCRIPTION
This section describes the FCS-717 List 4B COT shelf operational capabilities and lists the connector pinouts on
the backplane.
Operational Capabilities
Each system (one line unit and one to three channel units) can support up to 24 subscriber channels. Each channel
unit can provide four (4) or eight (8) channels, depending on the service offered. Services offered are:
• Plain Old Telephone Service (POTS)
• Integrated Services Digital Network (ISDN)
Table 1 and Table 2 on page 3 show how the FCS-717 List 4B utilizes channels, dependent on the channel unit
(four or eight channels) and the type of subscriber service (POTS, ISDN, or DDS) selected.
A label on the FCS-717 List 4B COT shelf indicates numbering for the line and
channel units. When the line units are a List 1 or 2, black numbers indicate sequential
channel unit numbering 1 through 9. When the line units are List 3 or higher, blue
numbers indicate channel unit numbering 1 through 3 for each of the three systems.
