Menu Option 8 Mapping the span line’s DS0s to chassis modems
The Total Control chassis contains 17 NAC slots. Two typical chassis
configurations are:
Configuration 1
Slot 1: T1/PRI Card
Slots 2–16: Quad Modem or Quad I-modem Cards
Slot 17: Network Management Card
Configuration 2
Slot 1: T1/PRI Card
Slots 2–15: Quad Modem/Quad I-modem Cards
Slot 16: NETServer or NETServer PRI Card
Slot 17: Network Management Card
Each of the slots populated by a Quad Modem Card contains four
modem channels numbered sequentially 1–4 from top to bottom.
This option allows you to map span line time slots to these modem
channels.
Use the following syntax when configuring this option:
DS0#:sl#/ch#
Where:
DS0#
= DS0 number (1–23)
sl#
= Chassis modem slot number (1–16)
ch#
= Chassis modem channel number (1–4)
When a modem is moved to a DS0, the DS0 it was associated with prior
to the move becomes unmapped.
