Configuration Tasks
Enabling the Interfaces on the Controller
To create the interfaces for the 8-Port Channelized T1/E1 SPA, complete these steps:
Command Purpose
Step 1
Router(config)# controller {t1 | e1}
slot/subslot/port
Selects the controller to configure and enters controller
configuration mode.
• t1—Specifies the T1 controller.
• e1—Specifies the E1 controller.
• slot/subslot/port—Specifies the location of the
interface. See the
“Specifying the Interface Address
on a SPA” section on page 15-6.
Step 2
Router(config-controller)# clock source
{internal | line}
Sets the clock source.
Note The clock source is set to internal if the opposite
end of the connection is set to line and the clock
source is set to line if the opposite end of the
connection is set to internal.
• internal—Specifies that the internal clock source is
used.
• line—Specifies that the network clock source is
used. This is the default for T1 and E1.
Step 3
Router(config-controller)# linecode {ami |
b8zs | hdb3}
Selects the linecode type.
• ami—Specifies Alternate Mark Inversion (AMI) as
the linecode type. Valid for T1 and E1 controllers.
Note After configuring the linecode as Alternate Mark
Inversion (AMI), you need to configure
invert-data by executing the invert-data
command from interface configuration mode.

• b8zs—Specifies binary 8-zero substitution (B8ZS)
as the linecode type. Valid for T1 controller only.
This is the default for T1 lines.
• hdb3—Specifies high-density binary 3 (HDB3) as
the linecode type. Valid for E1 controller only. This
is the default for E1 lines.
Step 4
For T1 controllers
Router(config-controller)# framing {sf |
esf}
For E1 controllers
Router(config-controller)# framing {crc4 |
no-crc4}
Selects the framing type.
• sf—Specifies Super Frame as the T1 frame type.
• esf—Specifies Extended Super Frame as the T1
frame type. This is the default for E1.
• crc4—Specifies CRC4 as the E1 frame type. This is
the default for E1.
• no-crc4—Specifies no CRC4 as the E1 frame type.
