Cisco ATUC-4DMT-ISDN Line Card
Installation and Configuration
Product Number: ATUC-1-4DMT-I(=)
Introduction
This publication contains instructions that describe how to install and configure
Cisco ATUC-4DMT-ISDN line cards. This high-density line card supports discrete multitone (DMT)
over Integrated Services Digital Network (ISDN) protocols that employ 2B1Q- or 4B3T-based
encoding.
You can only use this line card in Cisco 6260 digital subscriber line access multiplexers (DSLAMs) that
contain the NI-2 network interface processor module running Cisco IOS software. You can deploy the
line cards described in this document in either of two ways:
•
A direct connect configuration—Telco equipment routes DMT signals only between customer
modems and the line cards (see the "Line Card Direct Connect Deployment" section on page 11).
•
A splitter configuration—Telco equipment includes DMT/ISDN splitters to separate or combine
ISDN and DMT signals at the central office (CO) and at the customer site (see the "Line Card
Splitter Deployment" section on page 13).

Page 11: Line Card Direct Connect Deployment
In direct connect deployments, Cisco ATUC-4DMT-ISDN line cards are a principal component of the Cisco 6260 DSLAM normally located in a CO facility rack. You install from 1 to N (where N has any value up to 30) line cards in a single Cisco 6260 DSLAM. - Page 12 Cisco 677i Modem At a customer site, you must use the Cisco 677i modem to provide the Ethernet LAN interface (see Figure 4) at the downstream end of the line. The 677i modem provides the interface between a customer Ethernet and a line card.

Page 13: Line Card Splitter Deployment
A full complement of line cards in a single Cisco 6260 DSLAM can handle network communications from and to as many as 120 customers. You can install up to four Cisco 6260 DSLAMs, populated with ATUC-4DMT-ISDN line cards in a direct connect configuration, in a standard NEBS compliant 7-foot CO facility rack. - Page 14 In DMT/ISDN line card deployments, you use CPE and CO splitters to separate the two signals. DMT/ISDN splitters permit both telephone voice and data signals to be transported as data from and to the CPE. You can install as many as 30 ATUC-4DMT-ISDN line cards in a single splitter-configured Cisco 6260 DSLAM.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: Turn the television or radio antenna until the interference stops. -
