> LS Port Card: • N+1 EPS protection (N=1...6).
− Spare Board has to be plugged in the slot 32. The same access cards are shared between main and spare ports.
− Only one protection scheme
> HS Port Card: • N+1 EPS protection only for HS electrical ports (N=1....15 with max 8
protection schemes). The constraints are the following: − for the protecting port the corresponding access card has to be an HPROT
access card (without connectors) − the protecting card has to be plugged at the left side of the protected port or
ports (the same rule has to be respected by the corresponding access cards).
− the main/spare ports have to be adjacent.

> EPS protection is applicable to the PDH/SDH traffic cards with electrical interfaces. In the latter case the EPS is applied to the interface traffic card only; the access module cards are part of the line and unprotected. General characteristics of the EPS protection mode are:
> Switching criteria: card-missing, card-fail
> Switching time: max 50ms • Operation mode:
− 1+1 EPS always non-revertive − N+1 EPS always revertive w/ fixed WTR = 5 minutes
> External commands to control the switch position: Manual, Force, Lockout, Clear
