G.703/Expansion Data
The type of connector(s) at this location on the rear panel depends on
several factors: the type of interface required by the customer premises
equipment (CPE) and whether or not the radio is part of a protected
(redundant) configuration. See Table 8 for details.
NOTES:
1. The capacity of the 4E1 interface can be reduced to one (1E1) or two circuits (2E1).
See linemap command on
Page 66, for configuration information.
2. For RJ-45 pinout information, see
Figure 36 on Page 128.
3. This 68-pin interface connector is used only to pass the user data interface, the
Service Channel, and the orderwire circuits to the Protected Switch Chassis for
distribution. Fully-wired DB-68 computer cables (commonly used to interconnect
SCSI computer devices) can be used with this data port connector.
Ethernet
The ETHERNET connector provides access to the embedded SNMP
agent and other elements of the TCP/IP network-management interface.
The connector is a standard 10Base-T connection with an RJ-45 mod-
ular connector. The LEDR Ethernet connections are provided for remote
equipment management (NMS).
Ethernet in
a Repeater
Configuration
At a repeater site with two LEDR radios, the ETHERNET connectors of
each chassis must be connected to each other through a cross-connect
cable or using standard cables to an Ethernet hub. This inter-chassis
Ethernet connection must be made in order for the Orderwire and Ser-
vice Channel to function properly. (See Figure 13 on Page 21 for further
information.)
