Layer 1 Software Feature Descriptions

Cisco IOS Release 12.0(27)S1

DS1 Features

DS1s can be configured and monitored on a per-T1 channel basis. The 1-Port CHOC-12 ISE line card

supports the following DS1 features:

• Framing control— Extended Superframe (ESF) and Super Frame (SF) support

• ESF statistics

• Internal and line clocking modes

• Local (diagnostic), network (line), and remote loopback (including SF inband)

• BER Test at DS1 level

• Receive and transmit alarm processing

• Performance and Error Counters

E1 Features

E1s can be configured and monitored at the individual E1 channel level. The 1-Port CHOC-12 ISE line

card supports the following E1 features:

• Framing control—E1 and E1 -CRC, as well as Unframed

• Internal and line clocking mode

• Local (diagnostic) and network (line) loopback

• BER Test at E1 level

• Receive and transmit alarm processing

• Performance and error counters

Automatic Protection Switching

Automatic Protection Switching (APS) provides redundancy on SONET equipment to guard against line

failures. The 1-Port CHOC-12 ISE line card supports the following APS features:

• SONET Linear APS 1+1 mode.

• Bi-directional and Uni-directional modes.

• Linear APS is defined to provide protection at the line layer. Therefore all of the STS SPEs carried

in an OC-12 signal are protected together (That is, if a switch occurs, all of the STS SPEs are

switched together).

• Working and Protect channel can be on the same router, or in different routers.

Online Insertion and Removal

The Online Insertion and Removal feature (OIR) permits the removal or insertion of a

1-Port CHOC-12 ISE line card without disrupting the packet forwarding or routing of other line cards

operating in the same chassis. For additional information on OIR, see the document,
