SS7 configurations
The SS7 link interface can be one of the following:
•
A single timeslot on direct connected T1/E1 trunks.
•
All of the timeslots on a T1/E1 trunk. High speed links (HSL) meet the ANSI
T1.111-1996 and Q.703/Annex A standards. Each HSL occupies a full (not
channelized) T1/E1 line and transfers data at the rate of 1.544 (2.048) Mbps.
•
A single timeslot on a T1/E1 trunk carrying media. The H.100 bus delivers the
signaling link to the SS7 signaling interface.
These connections differ depending whether the node is set up in a dedicated
signaling or embedded signaling configuration. The default ISUP configuration that is
shipped is an embedded signaling configuration, which leverages the H.100 bus.
In an SS7 dedicated signaling configuration, none of the bearer trunks carry
signaling information. Instead, separate dedicated trunks carry this information.
