Chapter 7 Configuring the Channelized 12-port CT3/T1 Optical Services Modules
Configuring the Interfaces
Note
IP addresses can not be assigned to main interfaces configured for Frame Relay.
To configure the unchannelized DS3 interfaces, perform this task:
This is an example of an unchannelized DS3 interface configuration:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller t3 3/0
Router (config-controller)#
no channelized
Router (config-controller)#
exit
Router (config)#
interface serial 1/0
Router (config-if)#
dsu bandwidth 16000
Router (config-if)#
encapsulation ppp
Router (config-if)#
no shutdown
Router (config-if)#
exit
Router(config)#
Command
Purpose
Step 1
Router#
configure terminal
Enters configuration mode and specifies that the
console terminal is the source of the configuration
subcommands.
Step 2
Router(config)#
interface serial
slot/port
Specifies the serial port to configure.
Step 3
Router(config-if)#
framing {c-bit
|
m23
}
Specifies the framing.
Step 4
Router(config-if)# [
no
]
dsu bandwidth
Kilobits
/
sec
Sets the DSU subrate bandwidth.
Router(config-if)#
[
no
]
dsu mode
{0 | 1 | 2 | 3 | 4}
Specifies the DSU mode:
0–Digital-Link
1–Kentrox
2–Larscom
3–Adtran
4–Verilink
Step 5
Router(config-if)# [
no
]
dsu remote
[
accept
|
fullrate
]
Specifies if the local (near-end) interface will
accept incoming requests from the remote
(far-end) interface, or if the local interface will
request that the remote interface set its bandwidth to
fullrate.
Step 6
Router(config-if)#
encapsulation hdlc
|
ppp
Specifies the encapsulation type. HDLC is the
default encapsulation.
Step 7
Router(config-if)# [
no
]
clock source
{
internal
|
line
}
(Optional) Specifies the clock source.
Default is
line
.
Step 8
Router(config-if)# [
no
]
loopback
{
local
|
network
|
remote
{
line
|
payload
}}
(Optional) Sets the loopback mode.
Default is
no loopback
.
Step 9
Router(config-if)# [
no
]
cablelength
feet
Specifies the cable length. Default is 224.
Step 10
Router(config-if)# [
no
]
keepalive
Turns on and off keepalive messages.
Step 11
Router(config-if)#
no shutdown
Enables the interface.
