R2 Signaling is a particular framing type commonly found in Korea and other locations outside of
North America. With 7.3 software, this feature will be available for Korean markets only. This
feature allows the CyberSWITCH to accept incoming calls and create outgoing calls over E1 lines
provisioned for R2 signaling. The CyberSWITCH treats the R2 user or device just as it would a
digital modem user.
To use R2 signaling, you must enable the R2 signaling option for an E1 PRI data line in CFGEDIT.
You may configure individual channels on the line for dedicated access or frame relay access,
provided that the sixteenth time slot of the frame remains available for line signaling, and the line
signaling bits associated with the access remain idle.
Prerequisites for using R2 signaling:
•
Use with a PRI-23/30 resource only. This resource has the proper hardware support to enable
the signaling stack. Refer to the
PRI-23/30
switch settings.
•
Use with a DM-24+ or DM-30+digital modem resource. (The system relies on digital modems
for signaling and connecting incoming calls).
•
Configure R2 users or devices for digital modem access. The dialout phone number for an R2
user will be under the digital modem configuration.
•
Do not mix R2 and normal ISDN traffic on the same E1 interface.
•
If mixing R2 and ISDN resources within the same CyberSWITCH, be sure to use the Bandwidth
Reservation feature in order to insure that outgoing calls are made over the proper lines.
•
When using E1/R2 signaling, the CyberSWITCH supports a maximum of 3 PRI resources and
3 digital modem resources per system.
•
There is a one signaling session per incoming channel.

NFORMATION
A subaddress may be configured for a point-multipoint line. This element is a call screening
method. A subaddress is only needed if you have a line interface type of point-multipoint, and you
choose the subaddress call screening method.
