Version 7.0 27 Mediant 3000
Hardware Installation Manual 3. Physical Description
Interface Port Label Description
Instead of RJ-45 ports, 1000Base-SX
1.25 Gbps multi-mode optical SFP
transceiver using 850 nm wavelength
can be provided (customer ordered). In
such a setup, the connection to the LAN
is through fiber optic cables.
For full capacity and functionality, the
device must be connected with a 1-
Gbps link.
Notes:
• RTM-6310 provides T3 and STM-1/OC-3 interfaces. However, only one interface type
can be supported per deployment (software configurable, using the
PSTNTransmissionType ini file parameter).
• Unused SFP transceiver modules must be covered with dust / EMI plugs (see Section
6.7 on page 85).
• Un-assembled SFP cages must be covered with protective dust plugs (see Section
6.7 on page 85).
• ATM interface is reserved for future use.
3.3.3 RTM-6310 Redundancy Rear Transition Module
The RTM-6310 Redundant RTM is used for the HA mode. RTM-6310 Redundant is housed
in Slot #3 in the rear panel. It provides the Ethernet interface to the redundant TP-6310
blade housed in Slot #3 in the front panel, upon failure of the TP-6310 blade in Slot #1.
Upon TP-6310 failure, the standby TP-6310 blade switches the I/O interfaces of RTM-6310
from the failed TP-6310 blade to the standby TP-6310 blade. RTM-6310 Redundant re-
routes all calls from the failed blade to the currently active blade (previously redundant), by
relaying the interface between RTM-6310 and the newly active blade.
RTM-6310 Redundant also supports GbE link redundancy, by providing two Ethernet ports.
These ports are available (customer ordered) as either 10/100/1000Base-TX RJ-45 or
optical SFP GbE connectors.
