all frm220/frm220a series rack mount cards are hot-swappable

and can be installed in a 20 slots (2u), or 8 slots (1u) rack-

mountable chassis with any combination of redundant hot

swappable ac, 24vdc or 48vdc power supplies, providing a

scalable solution that is space-efficient and cost-effective. the

rack mount cards can also be mounted in 4 slots, 2 slots, or 1

slot standalone housing with fixed ac/dc powered chassis. the

rack mount cards of frm220/frm220a series provide

telecommunication solutions for most applications. ctc union

offers a universal and cost-efficient transmission series for a

variety of fiber optic technologies (multimode, single mode,

wdm, cwdm) starting from converters and switches, to modems

and extending to intelligent voice/data multiplexer systems. the

products are designed as rack mount cards in combination with

various chassis types. the concept is to ensure an extremely

variable mixture of products at low storage costs for spares.

the frm220-nmc is a network management

controller card that can be placed in a compatible

frm220 series chassis to provide device

management functions. the management interface

supports a local rs-232 serial console or remote

tcp/ip management by telnet, http and snmp

protocols. the card is designed to be hot swapped so

that it may be field replaced without affecting any

online service of any other rack cards. the card also

supports online firmware upgrade from tftp server,

using any user interface, without affecting any other

inserted line card's transmissions. support for any

standard nms is provided by the included enterprise

mib file. ctc union also provides and maintains our

own ems (element management system) which is a

java based client/server manager for monitoring and

maintaining a large number of network elements

over a long period of time.
