Configuring the Cisco NI-1 DLSAM Equipment Module

The Cisco 6100/6130 NI-1 DSLAM Equipment Module supports provisioning of cross connections on Cisco 6100/6130 NI-1 DSL access concentrators. The Cisco 6100/6130 DSL access multiplexer (DSLAM) is an ATM cell switch that multiplexes traffic from subscriber ports to a single ATM WAN port. Its 32 slot multiport line-card architecture can support ADSL and SDSL technologies.

Supported Configurations

Two configurations are possible with this system:

•Subscriber Connection Configurations

•Subtending Configurations

Subscriber Connection Configurations

Subscriber Connection configurations include the following:

•Direct Connect Configuration.

This involves connecting one subscriber directly to a modem (ATU-C or STU-C). Traffic is multiplexed from up to 64 ADSL or 128 SDSL subscriber ports to a single ATM WAN port.

•Digital Off-Hook Configuration (DOH).

This configuration uses a combination of a Multiplexer Chassis (MC), Line Concentration Chassis (LCC), and POTS Splitter Chassis (PSC) to provide the highest subscriber concentration. This configuration uses ADSL technology to support up to 400 ADSL users through 64 ADSL modem ports, allowing connections to be made when they are needed (i.e., dial up). If a connection is not established, the central office modem resources are made available to another CPE.

Subtending Configurations

Subtending Configurations include the following:

•Non-subtended Network Configuration.

Allows individual DSLAMs to be directly linked to the WAN via a trunk that comes from the WAN port.
