Provides emulated-OPX from a PBX to remote stations using FXS and
FXO connection. When FXS interworks with FXO, FXO and FXS should
be directly connected between switches. When FXS connects to FXO,
signaling should be matched using either ground-start or loop-start signaling.
FXO provides better disconnect supervision than FXS. In this case,
disconnect supervision means the function to notice the fact that other party
hung up call. Ground start provides this function, but connection should be
formed after understanding the characters of PBX due to the fact that all the
PBXs do not possess FXS/FXO port supporting ground-start.

Groundstart signaling
Generally used for trunk lines. Because it is the signaling type devised to
complement defects of FXS/FXO, E & M connection is preferable to
FXS/FXO. E & M connections from routers to telephone switches or to
PBXs provide better answer and disconnect supervision.
E & M signaling has many advantages over the previous CAS signaling
methods discussed in this document. It provides both disconnect and answer
supervision as well as glare avoidance. E & M signaling is simple to
understand and is the preferred choice when you use CAS.
Trunk Information Management
Requirements
Prerequisites
Before you attempt this configuration, ensure that you meet these
prerequisites:
y
T1-CAS signaling applies to T1 trunk only
y
In order to run T1-CAS signalings on the UBIGATE IBG2016 routers, these
hardwards are required:
−
WTE-2M or WTE-4
y
Define the command cas-ds0-group on the T1 trunk(module) to create ds0-
group.
y
Use the command voice-port in order to choose a proper signaling and its
subsequent properties
