X4IP option card (
TransLAN
®
)
On the 1643 AM / 1643 AMS an Ethernet LAN option board (X4IP) is available
providing four 10/100BASE-T Ethernet interfaces. This option board is based on
TransLAN
®
. When equipped with a TransLAN
®
option board, Alcatel-Lucent SDH
multiplexers can offer 10/100BASE-T Ethernet interfaces.
The LAN interfaces that are supported are 10BASE-T and 100BASE-TX. The numbers
″10″ and ″100″ indicate the bit-rate of the LAN, 10 Mbit/s and 100 Mbit/s respectively.
The ″T″ or ″TX″ indicates the wiring and connector type: Twisted pair wiring with
RJ-45 connectors. The actual LAN speed does not need to be configured, since the
Ethernet interfaces support the auto-negotiation protocol, which enables them to select
the proper LAN speed automatically. The auto-negotiation function on the TransLAN
®
board is configurable per LAN port. This feature allows the auto-negotiation function
to be manually overridden from the Lucent OMS or the ITM-CIT. If this
auto-negotiation function is disabled, it is possible to select a specific operational mode
(10 or 100BASE-T, Half/Full-Duplex).
The X4IP option card supports Enhanced Flow Classification - IEEE 802.1Q mode and
IEEE 801.2ad mode. Network traffic from end users can be classified into flow
categories on the edge ports of a TransLAN® domain. As a result, ports can be
provisioned as “Edge” or “Interior” ports. Edge ports are either Customer Role ports
(UNI) or “Virtual ports” on a Trunk port (E-NNI). A virtual port is the traffic over a
trunk port belonging to a single end-user and is characterized by an S-VID tag.
On edge ports, up to seven provisionable flows can be defined with a combination of
the following criteria:
• port
• C-Tag (C-VID, C-UP) previously known as: VID, UP
• IP-TOS field (DSCP)
• Destination Address Mask (for broadcast/multicast and for customer control traffic)
