TIME DIVISION MULTIPLEXER (TDM)/MULTICHANNEL MULTIPOINT

(MCMP) OPTION

Increased flexibility in network design and implementation is an important advantage of the Time

Division Multiplexer/Digital Sharing Device (TDM/DSD 'Flex') option, while providing cost-effective

data networking alternatives. The TDM/DSD 'Flex' function improves the use of digital facilities

through bandwidth control and allocation. The TDM/DSD 'Flex' option can be controlled by the 6700

Series NMS, the Shared Diagnostic Control Panel (SDCP), or the COMSPHERE 3610 front panel.

TDM

The TDM will multiplex up to six channels onto a single point-to-point digital facility. Configured

as a DSD, the DSU allows up to six polled-protocol devices to share a single point-to-point or multipoint

digital facility. Configured as a host port-sharing device, the TDM/DSD 'Flex' shares up to six

host ports for the primary purpose of disaster recovery. Three ports are used for the primary data path

and three ports for automatic 'hot' spare during a front end port failure. The versatile TDM/DSD 'Flex'

option when configured with the Dial Backup Module (DBM) card version, serves as the digital bridge

for multipoint single-call dial restoral applications.The TDM/DSD 'Flex' option requires an expanded

housing to the COMSPHERE 3610 standalone version and a separate card slot in the COMSPHERE

3000 Series Carrier with the COMSPHERE 3611 card version.

MCMP

The MultiChannel MultiPoint (MCMP) option builds on TDM/DSD features by supporting all

TDM/DSD functions while adding MCMP functions to create one of the most powerful and flexible

DSUs in the industry. The sophisticated MCMP option uses a patented technology to consolidate

multiple applications and protocols over a single multipoint digital facility. Up to six individual data

channels can be configured for your multipoint circuit. Each channel is non-interfering with other

channels and protocol insensitive. These characteristics broaden the number of applications available

to allow both point-to-point and multipoint applications to work on the same mulitpoint circuit.

MCMP comes in both a two- and six-port standalone version that can be mixed on the same

circuit. This means you do not have to buy a six-port version for all remote sites (when all you need

is a two-port version at some sites and a six-port version at other sites). The unique any port to any

port mapping feature from the central site DSU to remote DSUs, adds flexibility to your configuration

choices. This unique mapping feature allows remote site configurations to support both MCMP and

DSD applications. As with the TDM/DSD option, up to two DSD groups can be configured or use the

digital bridge mode for multipoint single-call dial restoral applications.

MCMP (continued from page 3)

The TDM/MCMP option is supported by both the COMSPHERE 3610 standalone version and the COMSPHERE 3611 card version. The standalone

version provides 'Flex' function which allows each port to be configured as either RS232 or V.35 electrical. An expanded housing which provides

either one or five standard (DB25) connectors is required for either two- or six-port TDM/MCMP respectively. When V.35 electrical is selected, a DB25

to V.35 conversion cable is required for ports two through six. No conversion cable is required for port one because it is assigned to either an RS232D

or V.35 connector on the base DSU unit.

The card version supports two- or six-port TDM/MCMP with port one as either RS232D or V.35 connector and ports two through six as RS232. A

DB26 to V.35 connector cable is required when port one is assigned as a V.35 connection. Two-card slots are required to support TDM/MCMP in the

COMSPHERE 3000 Series Carrier. Thus, allowing a maximum of eight MCMP DSUs per carrier.

DIAL BACKUP MODULE (DBM) OPTIONS

The Dial Restoral option offers complete flexibility in all areas of user application recovery. Dial

Restoral provides automated, single-call, point-to-point and multipoint restoral over either the ISDN BRI

network, the two-wire Public Switched Telephone Network (PSTN), two-wire Switched 56 Digital

Network, or four-wire Switched 56 Digital Network.

Point-to-point restoral is accomplished using an integral Dial Backup Module (DBM). Dial line rates

supported for the ISDN BRI connection include full duplex, 56,000 or 64,000 bps operation. Dial line rates

supported for the PSTN connection include full duplex, 14,400 bps, 12,000 bps, 9,600 bps, 4,800 bps, or

2,400 bps operation.

The dial restoral connection can be controlled by the COMSPHERE 6700 Series NMS, the Shared

Diagnostic Control Panel (SDCP), or the COMSPHERE 3610 front panel. While in dial restoral mode, the

DSU automatically looks back to the digital facility and evaluates its health, switching back as soon as

service is restored. This automatic "lookback" feature helps minimize line costs by eliminating extended

long-distance line charges once the digital facility becomes operational again. Networks requiring continuous

availability can now attain uptime goals without dedicated around-the-clock staffing at the network

control center. An automated dial tone test during non-usage periods informs network operations if the

dial restoral circuit is disconnected. This eliminates the requirement for expensive and time-consuming

manual testing of dial restoral circuits by network operations.

In addition to its automatic restoral capabilities, the versatile Dial Restoral Option

features password and call-back security. When enabled, these security options prevent

unauthorized access and ensure integrity of the digital facility. A 10-number directory is capable of

selecting alternative destinations for the automated dial restoral process, as well as call-back

numbers for security.

Multipoint dial restoral is easy using the digital bridge feature of the card version TDM/MCMP option

and the DBMs, both of which are housed in the COMSPHERE 3000 Series Carrier. Each digital bridge

provides bridging for five remotes. Additional bridges can be interconnected to the first or primary bridge,

up to a maximum of six (including the primary bridge), to back-up a total of 25 remotes. The COMSPHERE

6700 Series NMS maintains complete control of the network during the multipoint restoral process.
