10g uplink ethernet aggregate switch card
description
the frm220a series is a ip based ethernet aggregation
platform, which incorporates a 24+4 port l2 ethernet switch
(frm220-gsw/snmp) or a new 20+4 port l2 gigabit ethernet
switch with 4+10gigabit uplink. the frm220a has a buil-in
gigabit ethernet backplane to interconnect the ethernet access
and e1 tdm based inverse multiplexer module cards with the
frm220a-gsw/snmp card.

the frm220a incorporates a 24+4 gigabit ethernet switch.
twenty
ports supply each slot of the 2u 20-slot chassis with an electrical
gigabit ethernet uplink with the remaining four electrical gigabit
ports accessible via the rear of the chassis. the additional four ports
are provided by sfp sockets. all eight gigabit ports (4+4) are usable
without restrictions for uplink aggregate to the ethernet metropolitan
area network (e-man). the frm220a-gsw/snmp card transmits
ethernet between the subscriber equipment (bridge/ modem or
network interface card) and the e-man. the card provides a user
networking interface with ethernet packets. this card is capable of
providing high bandwidth for assembling ethernet traffic. the card is
not only the system aggregate/trunk module, but also the system's
control module, providing oam management functions.
the frm220a-gsw/snmp-10g is the next generation
management module card of frm220a chassis. it is built in
gigabit ethernet interface to connect with backplane and link to
each slot of frm220a chassis. to aim at the metro ethernet
application, the specifications of frm220a-gsw/snmp-10g f
ully meet the attributes of carrier ethernet proposed by
mef (metro ethernet forum). it comply mef 9 standard to
support e-line/e-lan service, mef 14 standard to enable the
bandwidth profile configuration delivering
sla (service level agreement) for end-to-end performance
characteristics as well as mef21 to support carrier grade service
oam management rapidly detecting and recovering from the
network incidents in real time.
