MPX Connectors
The Traverse shelf uses MPX optical fiber connectors to provide high-density and
easy-operation fiber connection for SONET/SDH and Gigabit Ethernet (SX and LX)
optical interface cards. The MPX connector design specifically supports high fiber
density applications in accordance with Bellcore GR-1435-CORE generic requirements
for multi-fiber connectors. Each slot has receptacles for up to two MPX ribbon fiber
connectors. Each connector supports from 1 to 12 fiber pairs, for a maximum fiber
count of 48 per slot.

Timing Interface
The backplane provides primary and secondary T1/E1 and CC2M (Composite
Clock—64 kHz and 2 MHz) input and output timing interfaces, and primary and
secondary BITS input timing interfaces. These timing interfaces are routed to both
control cards, which distribute system timing references to all cards.
System and Environmental Alarms Interface
Support is provided for the full set of system alarm outputs, sixteen environmental
alarm inputs, a fail-safe alarm, and a remote alarm cut-off. The environmental
telemetry inputs and outputs are supported by the optional Environmental Alarm Card
located on the main backplane, which provides additional system-management
functions to accommodate customer-defined alarm input/output requirements. The card
is field replaceable and can be replaced without disconnecting the alarm wiring.
Modem Interface
The RS-232C modem interface uses a vertical 8-pin RJ-45 connector that is configured
as a data terminal equipment (DTE) port for connection to an external modem,
supporting dial-up remote access to the active control card. Dial-up access can also be
achieved by installing a terminal server on the DCN and communicating via Telnet to
any other Traverse node on the network. A local VT-100 terminal (or a PC with VT-100
terminal emulation software) can also be connected to the RS-232C connector
(Backplane interface).
Ethernet Connection to Data Communications Network
The Traverse system has a 10/100BaseT Ethernet interface that can be used to connect
a Traverse node to the TransNav system (or to another EMS) and to other remote
management devices. The RJ-45 signal connections are bridged to both the primary and
secondary control cards. This enables the TransNav management system to always talk
to the active control card, even after a protection switching.
In-band Management
A network of Traverse nodes can be managed over the service provider’s data
communications network (DCN) as long as at least one Traverse node is directly
connected to that network through the Traverse DCN Ethernet interface. Traverse
nodes that have no direct connection to a DCN can communicate with the EMS
indirectly, through any Traverse node that is connected to the DCN.
Out-of-band Management
A Traverse node that is not directly connected to a DCN is able to learn a route to
Traverse nodes on the DCN without any explicit local provisioning of routing
information, as long as it is connected via the Force10 Control Plane to one or more
gateway Traverse nodes. Service providers must use static IP routes to enable devices
on the DCN to reach both gateway and non-gateway Traverse nodes.

Traverse Hardware Guide, Release TR4.0.x 5
Quality of Service
Traverse IP quality of service (IP QoS) provides filters and priority queueing with
statistics for all the traffic going over the Traverse DCC network. Priority is given to
traffic originating from the Traverse network and the TransNav server. An access
control list (ACL) manages IP hosts and networks for IP forwarding action to allow or
block traffic. Classifiers and queues prioritize and manage the IP forwarding based on
high priority or best effort.
Proxy ARP Management
The Traverse supports proxy address resolution protocol (ARP) on the Ethernet DCN
interface. Proxy ARP is the technique in which one host, usually a router, answers ARP
requests intended for another machine. By faking its identity, the router accepts
responsibility for routing packets to the real destination. Using proxy ARP in a network
helps machines on one subnet reach remote subnets without configuring routing or a
default gateway.
Power Terminals
The Traverse receives redundant -48 VDC feeds from the PDAP (PDAP-4S,
PDAP-15A, or legacy PDAP-4S) or third-party power distribution unit and distributes
these to each slot. Each slot has access to both A and B -48 VDC power feeds.
Electrical Connector Cards for Electrical Interfaces
The electrical connector cards (ECMs) enable copper and coax network interface
cabling using industry-standard cables and connectors.

Guide, Chapter 2—“ECM Interface Specifications.”

supporting dial-up remote access to the active control card. Dial-up access can also be
achieved by installing a terminal server on the DCN and communicating via Telnet to
any other Traverse node on the network. A local VT-100 terminal (or a PC with VT-100
terminal emulation software) can also be connected to the RS-232C connector
(Backplane interface).
Ethernet Connection to Data Communications Network
The Traverse system has a 10/100BaseT Ethernet interface that can be used to connect
a Traverse node to the TransNav system (or to another EMS) and to other remote
management devices. The RJ-45 signal connections are bridged to both the primary and
secondary control cards. This enables the TransNav management system to always talk
to the active control card, even after a protection switching.
In-band Management
A network of Traverse nodes can be managed over the service provider’s data
communications network (DCN) as long as at least one Traverse node is directly
connected to that network through the Traverse DCN Ethernet interface. Traverse
nodes that have no direct connection to a DCN can communicate with the EMS
indirectly, through any Traverse node that is connected to the DCN.
Out-of-band Management
A Traverse node that is not directly connected to a DCN is able to learn a route to
Traverse nodes on the DCN without any explicit local provisioning of routing
information, as long as it is connected via the Force10 Control Plane to one or more
gateway Traverse nodes. Service providers must use static IP routes to enable devices
on the DCN to reach both gateway and non-gateway Traverse nodes.
Quality of Service
Traverse IP quality of service (IP QoS) provides filters and priority queueing with
statistics for all the traffic going over the Traverse DCC network. Priority is given to
traffic originating from the Traverse network and the TransNav server. An access
control list (ACL) manages IP hosts and networks for IP forwarding action to allow or
block traffic. Classifiers and queues prioritize and manage the IP forwarding based on
high priority or best effort.
Proxy ARP Management
The Traverse supports proxy address resolution protocol (ARP) on the Ethernet DCN
interface. Proxy ARP is the technique in which one host, usually a router, answers ARP
requests intended for another machine. By faking its identity, the router accepts
responsibility for routing packets to the real destination. Using proxy ARP in a network

helps machines on one subnet reach remote subnets without configuring routing or a
default gateway.
Power Terminals
The Traverse receives redundant -48 VDC feeds from the PDAP (PDAP-4S,
PDAP-15A, or legacy PDAP-4S) or third-party power distribution unit and distributes
these to each slot. Each slot has access to both A and B -48 VDC power feeds.
Electrical Connector Cards for Electrical Interfaces
The electrical connector cards (ECMs) enable copper and coax network interface
cabling using industry-standard cables and connectors.
