Automatic Protection Switching (APS)
provides for immediate facility back-up to protect the
most critical network locations. APS can be configured
for use with a single service provider or as a back
up using an alternate carrier. Verilink integrates two
versions of APS functionality, the TR54017 specification,
and Auto A/B.
Verilink’s implementation of
TR54017 enables automatic switching between two T1 lines
in the event of performance degradation or circuit failure.
Auto A/B line switching is a single-ended
A/B switch. Auto A/B allows seamless switching from
one service provider to another if the primary provider
can no longer carry service.
