The E1 I/O module provides eight E1 interfaces that can be allocated as either individual E1 network
trunk or subtend interfaces, or as IMA group trunk or subtend interfaces. The E1 I/O module also
provides the alarm pinouts and BITS clock input circuits for the Cisco 6260 system.
The E1 I/O module works with the DS3+T1/E1 IMA NI-2 card in the Cisco 6260 chassis.
