and RS-232
DTE Interface
The backplane DCN Ethernet and RS-232 DTE interfaces are supported by shielded
vertical 8-pin RJ-45 connectors on the main backplane.
Backplane DCN Ethernet.
The Traverse system provides a data communications
network (DCN) to connect a Traverse node to the TransNav Management System and
to other remote management devices. The DCN Ethernet interface is located on the
Traverse main backplane. Only the active GCM has a physical connection to the DCN
Ethernet RJ-45 connector. Ethernet signals are bridged to both the working and protect
General Control Module (GCM) cards for communication to Traverse nodes. This
enables the TransNav Management System to always talk to the working GCM, even
after a protection switch.
A network of Traverse nodes can be managed over the service provider’s DCN as long
as one Traverse node is directly connected to that network through the DCN Ethernet
interface. This node is referred to as the Traverse Management Gateway Node (MGN).
Traverse nodes that have no direct connection to a DCN can communicate with the
TransNav system indirectly, through the Traverse Management Gateway node via the
data communications channel (DCC) of an OC-12 or OC-48 card interface.
The backplane DCN Ethernet interface also allows telnet access directly to any
Traverse node in the network through the DCC.
The DCN Ethernet interface is a data terminal equipment (DTE) interface type,
supports both 10BaseT and 100BaseT, supports half- and full-duplex modes, and is
compliant to IEEE 802.3 signal definition for an 8-pin RJ-45 connector. Pinouts for the
DCN Ethernet interface are provided in the following table.
Note:
Although this interface is set to auto-negotiate between 10/100BaseT and half-
and full-duplex modes, Turin recommends a 100BaseT with half-duplex configuration.
