V5.2 Example Configuration Trace

Important! This release of V5.2 supports LE only.

Important! AN is not supported for V5.2. Any text or illustrations (for example, call flows) indicating the AN side is for clarification purposes only.

Overview

The following trace shows an example configuration for a system using the V5.2 protocol. In this example, both ends of the V5.2 interface are shown in one CSP system; the LE side and the AN side.

The following is a list of objects that the host must manage for this implementation of the V5.2 protocol:

V5 IDs

This example shows the host creating four new V5 IDs within the system. V5 IDs 0 and 2 are assigned for the LE side, and V5 IDs 1 and 3 are assigned for the AN side. These V5 IDs are logical entities that the host uses to manage the V5 interfaces within the system. Once the V5 IDs are created within the system, the host must associate link IDs with each V5 ID.

Links

Each V5 ID has associated links that carry the voice data. These links are logically represented as logical link IDs for each V5 ID. Each link ID corresponds to a unique logical span ID. Links can carry data only (no C Channels residing on them), or may contain C Channels that carry the signaling information for the V5.2 protocol and data.

Attributes

Add links

Remove links

Contains

Associated C Channels

C Channels

Each V5 ID within the system has a corresponding C Channel. The host must manage logical C Channel IDs for each V5 ID within the system. For the V5.2 protocol, there is a primary C Channel and a secondary C Channel for redundancy. The C Channels must reside on timeslot 16 of the links on which they are assigned.

Attributes

Add C Channel

Remove C Channel

Logical Span IDs

The host must manage logical span IDs within the CSP system. Logical span IDs are assigned to the physical trunk interfaces to terminate E1 spans. These logical span IDs are associated with the V5 link IDs. The host associates the span IDs with the link IDs when configuring the links using the add link TLV contained within the V5 configure message.

User Ports

A group of user port IDs are assigned by the host, to each V5 ID within the system. A user port ID represents an actual user of the service.

This example shows:

De-assigning any previously configured spans within the system

Assigning eight logical span IDs to the physical E1 span IDs (0-7)

Formatting the E1 spans to clear channel

Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.
A digital communications link - voice, data, and video at a 2.048 Mbps rate; 30B/2D or 31B/1D (ISDN); non-North American version of T1.
Tag-Length-Value block. A standardized block that allows data to inserted in a standard way into API messages.
The point in the Excel platform where a DS0 connects to a network. Also known as a "socket."
