System planning and ordering 39System selectionDetermine the type of Fiber Remote IPE enclosure. This selection can bedictated by the installation preference, blocking considerations, and thenumber of IPE cards required at the remote site.If planning a floor-standing system, select the modular column. If planninga wall-mounted system, select the cabinet.In some applications where non-blocking or low blocking trafficconsiderations are important, it is necessary to limit the number ofperipheral cards supported by each Fiber Peripheral Controller card. Fora non-blocking condition, the 120 voice/data timeslots support seven oreight 16-port line cards. Each additional line card in the IPE module or thewall-mounted cabinet increases call blocking under high traffic conditions.Refer to Communication Server 1000M and Meridian 1 Large SystemPlanning and Engineering (NN43021-220) () to calculate traffic.The system type can also be dictated by the number of ports required atthe remote site. The modular column configuration supports 16 line cardsand provides a maximum of 256 ports. This column can be expanded byadding a second IPE module to support an additional 256 ports. Each IPEmodule requires a Fiber Peripheral Controller card at the remote site and acorresponding Fiber Superloop Network card at the local site.In addition to line cards, the Fiber Remote IPE supports all the cardsthat do not require external connection to the local common or networkequipment.The wall-mounted configuration supports 10 line cards. The wall-mountedsystem can be used if the system size requirement is less then ten IPEcards. To expand this type of system beyond ten IPE cards, add anexpansion cabinet adjacent to the main cabinet, and install up to six IPEcards into the first six IPE card slots of the expansion cabinet.Fiber Remote IPE site planningWhen selecting a site for the Fiber Remote IPE, consider the number ofports currently required at the site and the possibility of expansion to meetfuture needs. As well, consider environmental, power, and cable-routingrequirements.Environmental requirementsFiber Remote IPE equipment conforms to the same environmentalrequirements as the rest of the system equipment. Temperature, humidity,and altitude for equipment operation should not exceed the specificationsshown in Table 4 "Environmental requirements" (page 40).Nortel Communication Server 1000Fiber Remote IPE FundamentalsNN43021-554 04.01 4 June 2010Copyright © 2007-2010 Nortel Networks.
