Configuring Span Lines 1 and 2 2-5

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.
