Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+
Configuring an Unchannelized T3 Link
Examples follow:
•
Instruct the PA-MC-2T3+ to use a line clock source.
The example that follows is for a port adapter on a VIP in interface processor slot 1:
Router(config)#
interface serial 1/0/0
Router(config-if)#
clock source line
The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:
Router(config)#
interface serial 1/0
Router(config-if)#
clock source line
•
Instruct the PA-MC-2T3+ to use an internal clock source.
The example that follows is for a port adapter on a VIP in interface processor slot 1:
Router(config)#
interface serial 1/0/0
Router(config-if)#
clock source internal
The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:
Router(config)#
interface serial 1/0
Router(config-if)#
clock source internal
Configuring MDL Messages for the Serial Interface
You can configure Maintenance Data Link (MDL) messages (which are defined in the ANSI
T1.107a-1990 specification) on the PA-MC-2T3+.
Note
MDL messages are only supported when the T3 framing is set for c-bit parity. (See the
Framing Type for the Serial Interface” section on page 4-6
To configure MDL messages, use the interface commands:
mdl
{
transmit
{
path
|
idle-signal
|
test-signal
} |
string
{
eic
|
lic
|
fic
|
unit
|
pfi
|
port
|
generator
}
string
}
no mdl
{
transmit
{
path
|
idle-signal
|
test-signal
} |
string
{
eic
|
lic
|
fic
|
unit
|
pfi
|
port
|
generator
}
string
}
where:
•
eic
is the equipment identification code (up to 10 characters).
•
lic
is the location identification code (up to 11 characters).
•
fic
is the frame identification code (up to 10 characters).
•
unit
is the unit identification code (up to 6 characters).
•
pfi
is the facility identification code to send in the MDL path message (up to 38 characters).
•
port
is the equipment port, which initiates the idle signal, to send in the MDL idle signal message
(up to 38 characters).
•
generator
is the generator number to send in the MDL test signal message (up to 38 characters).
Use the
no
form of this command to remove MDL messages. The default is that no MDL message is
configured.
