iAccess ™ Ethernet Aggregation Platform


Gigabit Ethernet Aggregate switch card


10G uplink Ethernet Aggregate switch card


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.
