The SIP PH supports an external interface, the LLE2 paddle board.
The LLE2 paddle board terminates an Ethernet connection which
provides the connection to the layer 2 switch or router.
Timing
No changes.
Configuration
The SIP PHs are configured as processor groups each having one or
two PHs. When configured with two PHs in a processor group, both
PHs are active with one being designated as serving and the other PH
as non-serving. Refer to section“Serving/Non-Serving” (2-30) for
additional information.
The GQPHs are configured as active loadshared PHs with a standby
spare PH.
