DESCRIPTION

■

Megaplex-2100 is a flexible E1/T1

multiplexer, enabling the integration of

multiple dedicated data, Frame Relay

data, voice, ISDN, video and LAN

channels onto TDM, Frame Relay or

hybrid main links.

■

Megaplex-2100's modular design,

together with a wide choice of hub

configurations and I/O modules

ensure the flexibility to support

applications ranging from small

campus networks to multi-site

corporate networks or extensive

carrier access solutions. Due to its

standards-adherence, central-office-

based cross connect units can

separate voice and data, sending

each to the appropriate carrier or

service.

■

In order to support the needs of

different applications, Megaplex-2100

is available in four different basic unit

chassis variants.

For customer premises applications

the following variants are available:

–

Megaplex-2100

(4U high) chassis

–

Megaplex-2104

(2U high) chassis.

For rack-mount installation in carrier

and service provider environments,

two additional variants are available:

–

Megaplex-2100B

(6U high) with

connectors on back (ANSI standard)

for the North American market

–

Megaplex-2100F

(10U high) with

connectors on chassis front (ETSI

standard) for the European market.

Both Megaplex-2100B and

Megaplex-2100F chassis allow

swapping modules without

disconnecting cables.

■

Redundant common logic and

power supply help to ensure a high

level of system reliability on the

Megaplex-2100 hubs. In addition, all

the hubs can support one or two main

E1 or T1 links, e.g. load sharing or

drop & insert and ring topologies or

redundancy. The main links support

options of integrated CSU/DSU and

LTU, or direct connection to fiber

optic cable.

■

To support Frame Relay together

with TDM technology, a special

Megaplex-2100/H version with a

hybrid common logic is available (for

MP-2100/4 units only). The hybrid

common logic enables management

of the Megaplex-2100/H with a

dedicated time slot over Frame Relay

networks. The Megaplex-2100/H

uses two types of main link cards:

– Hybrid main link card which allows

configuration of each time slot for

Frame Relay or TDM

– Regular TDM main link card.

■

Megaplex-2100 is

standards-based, ensuring

compatibility in multi-vendor

environments worldwide.

The E1 and T1 TDM framing and

signaling, PCM and ADPCM voice

coding, data interfaces and LAN

internetworking all conform to

international standards.

■

Megaplex-2100 stores up to

10 different configuration databases

and can switch between them in case

of any network event. This feature

enables alternate routing in case of

failure.

■

In addition to ADPCM and PCM,

high quality voice compression using

the MPMLQ algorithm is supported,

ensuring maximum efficiency on the

main links. For example, 30 voice

circuits can be compressed down to 5

timeslots, leaving the remaining

timeslots for other applications such

as LAN, SNA and video traffic.
