Register Signaling
In the R2 protocol, register signaling is used during the call setup process to exchange
information about the calling and called party numbers and the calling party category. You can
use IMAT to define any of the specific tones used in R2 register signaling.
R2 register signals are defined as either forward or backward signals. Forward, or outgoing,
signals are generated by the originator of a call. Backward, or incoming, signals are generated
by the terminating end of a call. Forward and backward signals are grouped into the categories
shown in the following table.
Each R2 card has two E1 links. The R2 card occupies one DSU slot in the SX-2000 LIGHT or
the SX-2000 MICRO LIGHT. The R2 card can be installed with the power on and is
hot-swappable .
The physical connections to and from the R2 card are made at the rear of the cabinet. These
connections include:
• two E1 interfaces (RJ-45 connectors) for network connection
• an RS-232 port (DB9 connector) for administration and debugging
• an Ethernet™ port (RJ-45 connector) for in-house development and troubleshooting.
Note: The R2 card requires LIGHTWARE 30 Release 1 UR 1 or higher.
OPS Manager
OPS Manager is a complete telecommunications management tool that enables you to control
the maintenance and operation of a network of Mitel systems. See
OPS Manager for detailed
information to install, program, maintain, and troubleshoot OPS Manager. From the OPS
Manager station, you can perform the following functions on a single system or on network of
systems:
• Manage a network telephone directory
• Move, add, change, and delete users
• Integrate the network telephone directory with a directory service database
R2 Signaling
Signal direction Event Group Function
Forward (outgoing) Group I Transmits digit information.
Group II Transmits the category of the calling party (such as
a coin box) and calling line identification.
Backward (incoming) Group A Acknowledges Group I signals, and requests digit
information and the category and identification of
the calling party.
Group B Acknowledges Group II signals and transmits status
information about the called party (such as busy).
Group C Acknowledges Group I signals and requests digit
information for the calling party (optional).
