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 signaling channel is delivered
internally 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.
In an SS7 dedicated signaling configuration, none of the bearer trunks carry signaling
information. Instead, separate dedicated trunks carry this information.
