Cisco 6160 DSLAM Overview 181

As shown in Table 8-2, interfaces whose names begin with ATM1 through ATM34 are line card

interfaces. Ethernet0/0 is the interface for the LAN that connects the Cisco 6160 to its

management system. For line card interfaces, the number before the slash indicates the slot

number. The number after the slash indicates the interface or port number. For example, ATM5/4

is port 4 in slot 5.

Conﬁguring Line Cards

Before you can use the Flexicard, you need to conﬁgure a slot for a speciﬁc card type. Use this

command:

slot

slot# cardtype

slot# is the slot number; the range is 1 to 34. cardtype is the card type for which you want to

conﬁgure the slot. You must indicate the type of card. To conﬁgure the Quad Flexicard in slot 1

to use DMT modulation, you would enter the following:

lab-6160(config)#slot 1 ATUC-4FLEXIDMT

NOTE You can use show hardware command to ﬁnd out which cards are installed in the Cisco 6160

DSLAM.

Creating DSL Proﬁles

Except for a few dynamic operational modes, port conﬁguration takes place through a

conﬁguration proﬁle rather than by direct conﬁguration. A proﬁle is a named list of conﬁguration

parameters with a value assigned to each parameter. You can change the value of each

parameter in the proﬁle. To conﬁgure a subscriber, you need only attach the desired proﬁle

to that subscriber. When you change a parameter in a proﬁle, you change the value of that

parameter on all ports using that proﬁle. If you want to change a single port or a subset of

ports, you can copy the proﬁle, change the desired parameters, and then assign the new

proﬁle to the desired ports. Multiple ports can share the same proﬁle, but one port cannot

have more than one proﬁle. If you modify an existing proﬁle, that change takes effect on

every ADSL port linked to that proﬁle.

Every port is attached to a special proﬁle named “default” by default. You can modify the

default proﬁle (but not delete it). This is useful when you want to modify one or two default

parameters and apply this to every port in the system (rather than creating a new proﬁle with

minor changes and attaching it to every port in the system).

When you create a proﬁle, it inherits all the conﬁguration settings of the default proﬁle at the

time of creation. If you subsequently modify the special proﬁle default, the new changes to the

default do not propagate to the previously created proﬁles.
