RLC description

Product introduction

The Reach Line Card (RLC) emulates a standard Extended Digital Line Card
(XDLC) and provides Private Branch Exchange (PBX) functionality for
telephones at remote locations. The RLC supports up to 20 remote devices (with
a limit of eight Remote Gateway 9150 units for a single RLC). The total number
of simultaneous telephone calls cannot exceed the total number of RLC ports in
the host PBX. The RLC supports the following devices:
Remote Gateway 9110
Remote Gateway 9115
Remote Gateway 9150
Digital Telephone Internal IP Adapter
Digital Telephone External IP Adapter
You can configure each port on the RLC as if telephones were locally connected
to a standard XDLC. Existing digital trunks (PRI) or an integrated 10BaseT
Ethernet interface (Voice over IP) carry voice and signaling traffic as packets.
Note: The RLC defaults to a half-duplex 10BaseT Ethernet connection. You can
configure a full-duplex 10BaseT Ethernet connection through Configuration
Manager. When you configure a full-duplex 10BaseT Ethernet connection, the
RLC's Ethernet collision LED remains on solid (constantly lit). This does not
indicate collisions on the segment, but that Full duplex is enabled. In addition,
when you enable full-duplex Ethernet, you must also set the corresponding port
on the connected switch to 10 FULL Duplex. Remote Gateway 9100 Series
products do not support Auto negotiation of the Ethernet interface.
You can upload RLC firmware through a customer-provided Trivial File
Transfer Protocol (TFTP) server installed on the administration PC, through a
10BaseT Ethernet connection.
