Figure 8-2 Cisco 6160 DSLAM Chassis

NOTE You can install line cards of two or more different types in a single Cisco 6160 chassis.

However, mixing different types of cards (Flexi ADSL, SDSL, and/or IDSL) on the same

side of the chassis might result in decreased performance.

Basic Cisco 6160 DSLAM Conﬁguration

In this section, you will learn all the necessary information to successfully conﬁgure the

Cisco 6160 DSLAM.

Interface Numbering

Before you begin the conﬁguration, it is important to know the interface numbering scheme

used by the Cisco IOS software in the 6160. Interfaces whose names begin with ATM0 (ATM0/0,

ATM0/1, and so forth) are NI-2 card WAN interfaces. ATM0/0 is the ATM switch’s interface

with the processor. There is no need to conﬁgure ATM0/0 unless you plan to use in-band

management. ATM0/1 is the trunk port. ATM0/2 and ATM0/3, if present, are subtending interfaces.

Table 8-2 illustrates the interface numbering scheme for Cisco 6160 DSLAM.
