ISDN QSIG Basic Call
Network Calling Party Name Display
Network Calling Party Name Display (NCPND) is supported within the
Meridian Customer Defined Network only. When QSIG is involved in the
call setup, the existing NCPND operation on unsupported interfaces applies
on QSIG.
Network Message Service
Network Message Service (NMS) is only supported on the Meridian
Customer Defined Network. NMS operation on QSIG is the same as the
existing treatment for unsupported interfaces.
Network Ring Again
Network Ring Again signaling is supported within the Meridian Customer
Defined Network only. Network Ring Again requests which go through the
QSIG interface will not be supported.
Remote Virtual Queuing
Remote Virtual Queuing (RVQ) does not operate on the QSIG interface. The
existing RVQ operation on unsupported interfaces applies on the QSIG
interface.
Trunk Route Optimization
Trunk Route Optimization (TRO) is supported within an MCDN network
only. When a redirecting node sends a message to the originating node and
the TRO request is accepted, the new call will go through the QSIG interface
just as a normal basic call. However, TRO signaling will not be able to
operate on the QSIG interface.
Virtual Network Service
A QSIG link can be used as a B-channel for the Virtual Network Service
(VNS) over a private network. All VNS services are supported as normal.
QSIG is only used as a speech bearer.
The following packages are required for ISDN QSIG Basic Call services:
• Digit Display (DDSP) package 19;
• Integrated Services Digital Network (ISDN) package 145;
• Primary Rate Access (PRI) package 146;
