DS3x3 mapper

(NTN437AA)
The DS3x3 mapper has three DS3 ports and provides add/drop capability for
three DS3 signals. Each port functions independently and in the same way as
a DS3 mapper.

Equipping rules

Connectivity for the three DS3 signals at each slot is through the BNC 12-Port
Front I/O module (NTN452JA) on the OPTera Metro 3500 Shelf
(NTN476DA). On the OPTera Metro 3500 Universal Shelf (NTN476AH) you
must use the BNC 12-Port Front Enhanced I/O module (NTN452JH) or the
BNC 12-Port Rear I/O module (NTN452KA).
