R2 SIGNALING

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.

SUBADDRESSES

CONFIGURING A SUBADDRESS

USING CFGEDIT

1. To configure a subaddress, select ISDN Subaddress from the Physical Resources menu.

2. Enter the subaddress. The subaddress is supplied by your Carrier Service.

SUBADDRESS CONFIGURATION ELEMENTS

SUBADDRESS

The subaddress for the system.

SUBADDRESSES BACKGROUND INFORMATION

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.
