Setting the Card Type
To set the card type for the T1/E1 interfaces, complete these steps:
enable
configure terminal
card type t1 0 1
exit
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
This chapter provides the information about how to configure a T1 or E1 interface.
To set the card type for the T1/E1 interfaces, complete these steps:
enable
configure terminal
card type t1 0 1
exit
To configure T1 interface, use the following commands:
enable
configure terminal
controller t1 0/1/0
clock source internal
framing esf
cablelength short 110
linecode b8zs
no shut
exit
Note |
For T1 interface, the default frame mode is Extended Super Frame (ESF). |
To configure E1 interface, use the following commands:
enable
configure terminal
controller e1 0/1/0
clock source internal
framing crc4
linecode hdb3
no shut
exit
Note |
For E1 interface, the default frame mode is Cyclic Redundancy Check 4 (CRC4). |
Staring with Cisco IOS XE Cupertino 17.7.1, the cable length short values are modified for the following interface modules:
