Chapter 21 Configuring IMA Port Adapter Interfaces
Configuring the T1/E1 IMA Port Adapter
Example
The following example shows how to change the clock source to free running:
Switch(config)# interface atm 0/0/3
Switch(config-if)# clock source free-running
Displaying the T1/E1 IMA Interface Configuration
To display the physical T1/E1 IMA interface configuration, use the following EXEC command:
Example
The following example shows a T1 IMA ATM interface 0/0/3 configuration, including the change to the
clock source configuration from the previous section:
Switch# show controller atm 0/0/3
ATM0/0/3 is up
PAM State is UP
Firmware Version: 1.6
FPGA Version : 1.2
Boot version : 1.2
Port type: T1 Port rate: 1.5 Mbps Port medium: UTP
Step 3
Switch(config-if)# clock source {free-running |
loop-timed | network-derived}
Configures the type of clocking.
Step 4
Switch(config-if)# framing {esfadm | sfadm}
Switch(config-if)# framing {cleare1 | crc4adm |
pcm30adm}
Modifies the T1 IMA framing type.
Modifies the E1 IMA framing type.
Step 5
Switch(config-if)# lbo {long {gain26 | gain36}
{-15db | -22.5db | -7.5db | 0db}} | {short {133ft
| 266ft | 399ft | 533ft | 655ft}}
Switch(config-if)# lbo {long gain43 {120db |
75db} | short gain12 22db}
Modifies the T1IMA line build-out.
Modifies the E1 IMA line build-out.
Step 6
Switch(config-if)# loopback {cell | diagnostic |
line | local | payload | pif | remote {line {inband
| fdl {ansi | bellcore}} | payload [fdl ansi]}}
Switch(config-if)# loopback {cell | diagnostic |
line | payload | pif}
Configures the T1 line loopback.
Configures the E1 line loopback.
Step 7
Switch(config-if)# linecode {ami | b8zs}
Switch(config-if)# linecode {ami | hdb3}
Modifies the T1 line code format.
Modifies the E1 line code format.
Step 8
Switch(config-if)# fdl {ansi | att} Configures T1 FDL format.
Step 9
Switch(config-if)# yellow {detection |
generation}
Enables T1 yellow alarm detection.
Step 10
Switch(config-if)# national reserve bit-pattern Modifies the E1 national bits.
