• 4-port OC3/STM1 / 1-port OC12/STM4 Adapter cards for MLPPP access ports
or TDM CES (Cpipes) and TDM CESoETH (MEF 8) access ports with DS1/E1
channels, or on a network port configured for POS
• 4-port OC3/STM1 Clear Channel Adapter cards network side (configured for
POS operation).
SC-APS with TDM access is supported on DS3, DS1, E1, and DS0 (64 kb/s)
channels.
MC-APS is supported in bidirectional mode on:
• 2-port OC3/STM1 Channelized Adapter cards for TDM CES (Cpipes) and TDM
CESoETH with MEF 8 with DS3/DS1/E1/DS0 channels
• 4-port OC3/STM1 / 1-port OC12/STM4 Adapter cards for MLPPP access ports
or CES (Cpipes) and TDM CESoETH (MEF 8) access ports with DS1/E1
channels.
MC-APS with TDM access is supported on DS3, DS1, E1, and DS0 (64 kb/s)
channels. TDM SAP-to-SAP with MC-APS is not supported.
APS can be configured in SC-APS mode with both working and protection circuits on
the same node, or in MC-APS mode with the working and protection circuits
configured on separate nodes.
For SC-APS and MC-APS with MEF 8 services where the remote device performs
source MAC validation, the MAC address of the channel group in each of the
redundant interfaces may be configured to the same MAC address using the mac
CLI command.
Use the following CLI syntax to configure APS port parameters for an SC-APS
group.
CLI Syntax: config# port aps-id
aps
hold-time-aps {[lsignal-fail sf-time]
[lsignal-degrade sd-time]}
protect-circuit port-id
rdi-alarms {suppress | circuit}
revert-time minutes
switching-mode {bi-directional | uni-1plus1}
working-circuit port-id
The following CLI syntax shows an example of configuring ports for SC-APS. The
only mandatory configuration required to create an SC-APS group is to configure the
working and protection circuit.
Example: config# port aps-1
