Duplicated SPE Standby Packet Interface
Reset o f a pa cket inter fac e on th e stan dby SPE does not d isrup t ser vice and
results in a reset of all packet interfac es on the standby SPE. The following
conditions are necessary:
■Handshake communication i s up.
■The SPE ca rrier s are n ot loc ked with t he SPE-Sel ect s witc hes.
The following sequence oc curs:
1. Memory shadowing is turned off.
2. All standby pac ket interfaces are reset.
3. If the reset succeeds, shad owing is turned on, memor y refresh initiated,
and the packet is p ut into the standby state.
4. If the reset fails, the circuit pac k is put into the out-of-service state,
lowering the standby SPE’s state-of-health.
Duplicated SPE Active Packet InterfaceStandby SPE available
When a packet interface on the ac tive SPE of a duplicated system is spec ified, a
spon taneo us SPE int erch ange is fir st pe rfor med b y the syste m, ass uming that :
■The SPE ca rrier s are n ot loc ked with t he SPE-Sel ect s witc hes.
■Handshake communication i s up.
■The state of health of the standby SPE is not lower than that of the active.
If the se co ndit ions a re met , the i nterc hang e pl aces the ac tive SPE into t he
standby state, and then all standby pac ket interfaces are reset as in the above
case. Links are not disrupted , but due to the interchang e transient calls are
dropped and the terminal is logged off.
Standby SPE Not Available
If any of the three conditions listed above are not met, an SPE interchange is
prevented and the ac tive packet interface i s reset, resulting in disruption of all
links associated with the c ircuit pack (see the Caution ab ove). When the
interchange is prevented by lower state of health of the standb y, the standby
packet interfaces are also reset according to the seq uence listed ab ove.
