Note

The following section is only applicable to the DSC SWe on MA-RMS.

 

The following figure provides an example of possible configurations for processing and transmitting TDM data traffic through the PCE382 cards in a DSC SWe (on MA-RMS) system (Area A and Area B). This system may have one or both of these configurations.

Provisioning Traffic on the PCE382

 

Area A

The PCE382 may terminate up to 124 incoming signaling links on the DSC SWe (on MA-RMS) by mapping a Signaling Channel (may be LSL, Annex A, or ATM), a Ribbon internal value, to a port and timeslot combination (see the preceding figure). To complete the Signaling Channel’s path from the SS7 network through the DSC, you must associate this channel to an SS7 Link (may be LSL, Annex A, or ATM).

When you have associated the Signaling Channel that is terminating data to an SS7 link, this channel becomes available to MTP3 for routing. For information about associating a Signaling Channel to an SS7 link at MTP3, see Configuring Linksets and Links.

Note

You are not required to map Signaling Channels to M2PA links.

There is a one to one mapping between Signaling Channels and timeslots; for example, if you are terminating 12 signaling links, you can map 12 timeslots to 12 LSL Channels.

Area B

The Local Pass Through feature, an object of Voice Pass Through, transparently passes timeslots that are not terminated on a port of a PCE382 to another port on the same PCE382. These unused timeslots can then be accessed by other node equipment.

The information for configuring this scenario is described in section Configuring Local Pass Through on the I/O Cards.
