Ports
Port Types
Before a port can be configured, the slot must be provisioned with a card type and MDA type
specified.
The Alcatel-Lucent 7710 SR routers support the following port types:
• Ethernet — Supported Ethernet port types include:

Fast Ethernet (10/100BASE-T)

Gigabit (1000BASE-T)
7710 SR ports must be configured as either access or network. The default is network.

Access ports — Configured for customer facing traffic on which services are
configured. If a Service Access Port (SAP) is to be configured on the port or channel,
it must be configured as an access port or channel. When a port is configured for
access mode, the appropriate encapsulation type must be configured to distinguish the
services on the port or channel. Once a port has been configured for access mode, one
or more services can be configured on the port or channel depending on the
encapsulation value.

Network ports — Configured for network facing traffic. These ports participate in the
service provider transport or infrastructure network. Dot1q is supported on network
ports..
• SONET-SDH and TDM — Supported SONET-SDH and TDM port types include:

DS-3/E-3

OC3/STM-1

OC12/STM-4

OC48/STM-16
A SONET/SDH port/path or a TDM port/channel can be configured with the following
encapsulations depending on the MDA type:

Frame Relay

PPP

cHDLC
• ATM
Some MDAs support ATM encapsulation on SONET/SDH and TDM ports. The ATM cell
format and can be configured for either UNI or NNI cell format. The format is
configurable on a SONET/SDH or TDM port/channel path basis. All VCs on a path,
channel or port must use the same cell format.
