Traffic provisioning
LAN interfaces
1643 AM and 1643 AMS support up to four 10/100BASE-T LAN interfaces, as part of
the TransLAN
used.
1643 AM and 1643 AMS support up to eight Ethernet interfaces in Private Line mode,
when the X8PL option card is used. The X8PL board is a point-to-point Ethernet
solution without any switching capabilities. The Ethernet ports are directly connected
to the virtual concatenation groups (VCGs o flexible SDH Channel TTPs).
Main features of the X4IP-V2 and X8PL options cards
The following table lists the main features and differences of the two option cards
X4IP-V2 and X8PL which can be used for Ethernet applications:
X4IP-V2
4 ports
provides a Layer 2 switch
supports advanced networking applications
like ring connections or point-to-multi-
point connections
no LCAS (Link capacity adjustment
scheme) support
EoS (Ethernet over SDH) mapping or GFP
(Generic Framing Procedure)
X5IP Option card
The X5IP option card(item code X5IP) will combine X4IP and X8PL capabilities in
the following aspects, as compared to X4IP and X8PL card:
• GBE ports support
– 10/100/1000 BASE-T GE port(1 E)
– 1000BASE-X GE(1 O)
• 3 10/100 FE ports support
• Full flexible mapping low order VC12/VC3 termination
• LCAS for V12 (VC12-1v to VC12-63v) and VC3(VC3-1v to VC3-3v)
• High number of WAN ports (up to 8)
• LPT supported on all ports
