C-DOT 256P AN-RAX and RLC FEATURES

FEATURESProvides front end termination for PSTN subscribersSupports maximum of 248 PSTN subscribersConnected to Local Exchange (LE) over one or two E1 links using standard V5.2 Protocol as per ITU-T specifications G.964 & G.965 and ETSI specifications 300-324 & 300-347.Provides First/Second Level of remotingProvides a transparent link between subscriber and Local ExchangeProvides Calling Line Identification Presentation (CLIP) on 2 ports of LCC cardProvides 16KHz Metering Pulse and Calling Line Identification Presentation (CLIP) on 2 ports of each CCM cardProvides Reversal on all 8 ports of CCM cardProvides Man Machine Interface (MMI) using VT 100 dumb

FEATURES

Password ProtectionRequires no air-conditioningLow Power ConsumptionLine Testing can be performed locallyTransparently supports all subscribers feature as supported by Local Exchange (LE)For any feature related enhancements, the S/W changes are to be done on Local Exchange (LE) only

(Contd.)

HARDWAREConsists of two controller cards

AN RAX Controller Card (ARC Card)AN RAX Interface Card (ARI Card)

ARC card supports 2 E1 links toward Local ExchangeBoth the cards form a security block alongwith respective SPC cardsRedundancy in Controller Cards8 port LCC/CCM cards for Subscriber InterfaceRTC card for testing of subscriber ports
