32 Product descriptiontimeslots on the IVD bus. The timeslots on the IVD bus corresponddirectly to the peripheral line card loops.• Common channel signaling that handles the SSD signaling to andfrom the Fiber Superloop Network card. It receives signaling packetsfrom Fiber Superloop Network, checks for CRC errors, strips start/stopbits and sends the rest of data to the Fiber Peripheral Controller MPUfor processing. It also processes the signaling information in theopposite direction by receiving the messages from the MPU, adds CRCand start/stop bits, and transmits these as SSD messages to the FiberSuperloop Network over the fiber-optic link.Fiber-optic interfaceTwo NT1P63 Electro-optical packlets can be installed on each FiberPeripheral Controller card to provide redundant fiber-optic interfaces.The Fiber Peripheral Controller card can be equipped with only oneElectro-optical packlet for a nonredundant link operation. The fiber-opticinterface provides a 155.52 Mbps point-to-point transmission facility.The fiber-optic interface performs the following functions:• connects the local system to Remote IPE using a dedicated singlemode fiber-optic link• provides a synchronous communication channel between the FiberSuperloop Network card MPU and the Fiber Peripheral Controller cardMPU• uses buffers and transceivers to extend the MPU data, address, andcontrol buses to the Electro-optical packlet• uses one or, optionally, two Electro-optical packlets installed on theFiber Peripheral Controller card to provide redundant fiber-optic links• provides Electro-optical packlet version identification, which is storedin the packlet’s EEPROM• monitors transmission quality of the fiber-optic link; if the transmissionis degraded or fails, the Fiber Peripheral Controller card automaticallytransfers to the redundant link, if equippedEngineering guidelinesGeneral system engineering guidelines for Large Systems are describedin Communication Server 1000M and Meridian 1 Large System Planningand Engineering (NN43021-220) ().Nortel Communication Server 1000Fiber Remote IPE FundamentalsNN43021-554 04.01 4 June 2010Copyright © 2007-2010 Nortel Networks.
