Configuring the T3 Controller
To configure the T3 controller for the 2-Port and 4-Port Channelized T3 SPA, complete the following steps:
SUMMARY STEPS
1.
Router# configure terminal
2.
Router(config)# controller t3 slot/subslot/port
3.
Router(config-controller)# [no] channelized
4.
Router(config-controller)# framing {auto-detect | c-bit | m23}
5.
Router(config-controller)# clock source {internal | line}
6.
Router(config-controller)# cablelength {0 - 450}
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.Router# configure terminal
Step 1
Selects the controller to configure and enters controller configuration mode.Router(config)# controller t3
slot/subslot/port
Step 2
(Optional) Specifies the channelization mode.Router(config-controller)# [no]
channelized
Step 3
• channelized—In channelized mode, the T3 link can be channelized into
28 T1s, and each T1 can be further channelized into 24 DS0s. This is
the default.
• no channelized—In the unchannelized mode, the T3 link provides a
single high-speed data channel of 44210 kbps.
(Optional) Specifies the framing type in channelized mode.Router(config-controller)# framing
{auto-detect | c-bit | m23}
Step 4
• auto-detect—Detects the framing type at the device at the end of the line
and switches to that framing type. If both devices are set to auto-detect,
c-bit framing is used.
• c-bit—Specifies c-bit parity framing. This is the default.
• m23—Specifies M23 framing.
To set the framing type for an unchannelized T3, see the Configuring
T3 Framing, on page 247.
Note
(Optional) Specifies the clock source.Router(config-controller)# clock source
{internal | line}
Step 5
• internal—Specifies that the internal clock source is used. Default for
channelized mode.
• line—Specifies that the network clock source is used. Default for
unchannelized mode.
