Data Option Overview
Each port is configured for asynchronous V.24/RS-232, or synchronous V.11/
RS-422 data and cross-connected to one of up to six overhead ports (channels) on
each link (RAC or DAC 155oM)
8
.
These channels share the same overhead as the NMS and radio-radio internal
communication.
At intermediate sites, each configured channel must be re-directed to the next
RAC, or DAC 155oM. (An AUX is not required at intermediate sites).
At the destination site, each channel is directed to the required port on the AUX
plug-in.
The configuration flow is outlined in Figure 7-35.
AUX Plug-in configuration is described in AUX Configuration on page 7-88.
AUX Circuits configuration is described in Circuits Configuration - Auxiliary on
page 9-14.
Configuration Flow
The flow for AUX Data configuration for local, intermediate and destination
Nodes is shown in Figure 7-35 on page 7-86.
8
6 channels are available within the normal 512 kbps overhead. Refer to AUX Transport on Link
Overhead and Operating Rules on page 7-87.
Within a protected ring, Auxiliary Data circuits will be interrupted beyond a
break-point, and will not be restored until the ring unwraps.
