Fiber Peripheral Controller Card - Nortel 1000 Manual

28 Product description
The fiber-optic interface performs the following functions:
•
connects the local system to Remote IPE using a dedicated single
mode fiber-optic link
•
provides a synchronous communication channel between the Fiber
Superloop Network card MPU and the Fiber Peripheral Controller card
MPU
•
uses one or, optionally, two Electro-optical packlets installed on the
Fiber Superloop Network card to provide redundant fiber-optic links
•
uses buffers and transceivers to extend the MPU data, address, and
control buses to the Electro-optical packlet
•
provides Electro-optical packlet version identification, which is stored
in the packlet's EEPROM
•
monitors transmission quality of the fiber-optic link; if the transmission
is degraded or fails, the Fiber Superloop Network card automatically
transfers to the redundant link, if equipped

Fiber Peripheral Controller card

The NT1P62 Fiber Peripheral Controller card is a microprocessor-controlle
d peripheral interface between the Fiber Superloop Network card and the
Remote IPE line cards. To communicate with the Fiber Superloop Network
card, the Fiber Peripheral Controller card uses the Electro-optical interface
and the fiber-optic link. To communicate with the intelligent peripheral
equipment, the Fiber Peripheral Controller uses 16 full duplex serial loops,
one for each line card in the IPE module.
The Fiber Peripheral Controller card occupies one card slot in the IPE
module. The adjacent card slot is not the full width and must remain
empty; however, a dummy faceplate should be installed in this empty card
slot to provide a better air flow between cards. This is necessary because
a non-fiber Peripheral Controller card occupies two card slots in the IPE
module and the Fiber Peripheral Controller card that plugs into the same
card slot occupies only one card slot. The dummy faceplate is used in the
floor-standing IPE module but is not necessary in the wall-mounted IPE
cabinet.
The main Fiber Peripheral Controller card performs the following functions:
•
provides a single or redundant dedicated optical link to connect the
Remote IPE to the local system
•
assigns any of the 120 timeslots on the fiber-optic link to any timeslot
of the 16 full duplex serial loops assigned to line cards in the IPE
module
