Configuring Ports - Alcatel-Lucent 7705 Interface Configuration Manual

Configuring Ports

Before a port can be configured, the slot must be provisioned with a card type and the
adapter card type must be specified.
The 7705 SAR supports the following port types:
On the CLI, a port is identified using the format slot/mda/port, where slot identifies the IOM
card slot ID (always 1), mda identifies the physical slot in the chassis for the adapter card,
and port identifies the physical port on the adapter card; for example, 1/5/1.
Channelized ports are identified using the format slot/mda/port.channel-group-id, where slot
identifies the IOM card slot ID (always 1), mda identifies the physical slot in the chassis for
the adapter card, port identifies the physical port on the adapter card, and channel-group-id
identifies the DS1 or E1 channel group ID; for example, 1/5/1.20.
7705 SAR OS Interface Configuration Guide
• Ethernet — the 8-port Ethernet Adapter cards have six RJ-45 ports for
10/100BASE-T (Ethernet and Fast Ethernet) connections. The cards also have two
SFP ports for fiber or copper SFPs. Fast Ethernet and Gigabit (100 Mb/s and
1000 Mb/s) fiber connections and 10/100/1000BASE-T copper connections are
supported. This variety of connections enables the Ethernet Adapter card to be
connected to different devices at the customer site, including wireless basestations,
DSL modems, microwave boxes, and other auxiliary equipment. As well, with fiber
connections, the adapter card can be directly connected to the Metro Ethernet
Provider (MEP) central office. Version 2 of the 8-port Ethernet Adapter card also
supports synchronous Ethernet timing.
• TDM — the 16-port T1/E1 ASAP Adapter card supports TDM ports that can be
configured for DS1 or E1 operation. The card supports channelization down to the
DS0 level. All ports must be either T1 or E1; there cannot be a mix of the two types.
When the first port is configured, all other ports on the card must be set to the same
type. To change types, all ports must first be shut down.
• multilink bundles — the 16-port T1/E1 ASAP Adapter card supports multilink
bundles. A multilink bundle is a collection of channels on channelized ports that
physically reside on the same adapter card. Multilink bundles are used by providers
who offer either bandwidth-on-demand services or fractional bandwidth (DS3 or
E3) services. Multilink bundles are supported over PPP channels (MLPPP).
• IMA — the 16-port T1/E1 ASAP Adapter card supports Inverse Multiplexing over
ATM (IMA). IMA is a standard developed to address the increasing need for
bandwidth greater than the DS1 or E1 link speeds (1.544 or 2.048 Mb/s,
respectively) but less than higher link speeds such as DS3 (44.736 Mb/s). IMA
combines the transport bandwidth of multiple DS1 or E1 channels in a logical link
(called an IMA group) to provide scalable bandwidth.
• SONET/SDH ports— the 4-port OC3/STM1 Clear Channel Adapter card has four
hot-pluggable SFP-based ports that can be independently configured to be SONET
(OC3) or SDH (STM1)
