Configuring BT IUP on an SS7 Card

Purpose

This section describes how to configure BT IUP on an SS7 card.

Before you begin

Acquire the Originating Point Code (OPC) and Adjacent Point Code (APC) before configuring the SS7 stack.

Configuring BT IUP

Step | Action | API Message(s)
--- | --- | ---
1 | Assign and configure spans | Assign Logical Span ID T1/E1 Span Configure
2 | Configure SS7 cards | CCS Redundancy Configure
3 | Configure Signaling Stacks | SS7 Signaling Stack Configure
4 | Configure Signaling Link Sets | SS7 Signaling Link Set Configure
5 | Configure Signaling Links | SS7 Signaling Link Configure
6 | Configure Signaling Route(s) | SS7 Signaling Route Configure
7 | Assign Voice Circuits (CICs) | SS7 CIC Configure
8 | Bring spans, CICs and signaling links in-service | Service State Configure

The steps below are used for an SS7 card.

Configuration Sequence

Use the following configuration sequence to bring SS7 signaling links and voice circuits in service.

1. Assign and configure spans.

Assign Logical Span IDs to spans on T1, E1, or J1 line cards you want to use for SS7 with the Assign Logical Span ID message.

Set the span format to Clear Channel by using the T1 Span Configure or E1 Span Configure messages. This step prevents line cards from attempting to extract CAS signaling from the spans.

2. Configure SS7 cards.

Configure SS7 cards in the system as primary or secondary using the CCS Redundancy Configure message. Independent cards are assigned as a primary card. In a redundant pair of cards, one is assigned as the primary card and the other as the secondary.

Subsequent SS7 configuration messages are sent only to primary SS7 cards, which forward the configuration to the secondary card if there is one.

• When configured as a pair, SS7 cards operate in a primary/secondary mode with respect to the call control user part. Signaling links operate in a load-sharing mode.

• Configuration information can be retrieved with the CCS Redundancy Query message.

See Configuring SS7 Card Redundancy for more information.

See Signaling System Number Seven.
A number that addresses a node in a SS7 network.
The point code of the node adjacent to “own node” (SS7)
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.
Digital communications link - voice, data, and video at a 1.544 Mbps rate (24 64 Kbps channels)
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.
See Common Channel Signaling.
Link that connects to the same node
See Circuit Identification Codes.
The condition of a component at a given instant. The current "context" of a PPL object, such as Idle, Seizing, Answered. In PPL files, a State is represented by a circle.
Signaling technique where the full channel bandwidth is used for data transmission, while the framing and control bits (signaling) use a separate channel. No control or signaling is performed on this path. See B8ZS and ZBTSI.
