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.

The steps below are used for an SS7 card.
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.
