Modular chassis

The Megaplex family consists of the 4U-high

Megaplex-2100 with 12 slots and the 2U-high

Megaplex-2104 chassis with five slots − for both

I/O and main link modules. This allows for a mix

of a wide variety of data, voice, fax, and

LAN services. All Megaplex-2100 modules fit

both Megaplex-2100 and Megaplex-2104 chassis.

Main link modules

The single or dual E1/T1 and ML-IP main link

modules incorporate the DS0 matrix between

the I/O channels and each of the E1/T1 trunks.

The modules support 8 Mbps non-blocking cross

connect for any DS0 coming from either the

channels or from the trunks. Multiple fractional

E1/T1 ports are supported. These main links

support 1+1 protective switching for any E1/T1

port.

The eight E1/T1/DSL main links support a higher

capacity of 16 Mbps when used together with

the HS-12 module, but do not support

redundancy.

ML-IP

Three-port 10/100BaseT Ethernet uplink module

with up to 4 Mbps uplink capacity. This module

serves as the main link to the IP network,

placing the packetized TDM data stream from

the I/O modules onto the IP network in the

form of TDMoIP framing. The module is also

available with two fiber optic 100BaseFX

uplinks.

Four timing options are available:

•

Link receive clock

•

Internal crystal oscillator channel

•

Clock from any high speed module (HS-6N,

HS-12N, HS-S, HS-U, HS-703, HS-Q/N)

•

Station clock

Any clock source can be set as the fallback in the

event of primary clock source failure.

Ring support (E1/T1 and RFER)

The Megaplex supports various ring topologies

ensuring no single point of failure. E1/T1 ring

protection provides self-healing in less than five

seconds. Resilient Fast Ethernet Ring provides a

100 Mbps (up to 40 E1/50 T1) Ethernet ring with

self-healing in less than 50 msec.
