Card Slots and Types
DS3-12E and DS3N-12E Cards
The twelve-port DS3-12E and DS3N-12E cards provide enhanced performance
monitoring functions. By monitoring additional overhead in the DS-3 frame, subtle
network degradations are detected.

The DS3N-12E can operate as the protect card in a 1:N protection group. The
DS3-12E card can only function as the protect card for one other DS3-12E card. If
Software Release 3.0 or higher is used, the card uses all enhanced performance
monitoring functions. With software prior to Release 3.0, the card operates with the
same functions as the older DS-3 card.
With Software R3.1, R3.2, and R3.3 you can perform an in-service upgrade from the
DS3-12/DS3N-12 card to the DS3-12E/DS3N-12E card to take advantage of
enhanced PM functions without disrupting service.
