272 NT5D33 and NT5D34 Lineside E1 Interface cardsFigure 58CAS+ complianceKey Benefits of using CAS+ signaling (ELEI mode) over traditional A/B bitsignaling (LEI mode) include:1. Calling Line ID Presentation (CLIP)When an incoming call over the TDM/IP network or a CS 1000 originatedcall is directed towards the CAS+ compliant system, Calling Line ID canbe provided over the CAS+ interface. This is assuming that the incomingcall has the CLID without any presentation restrictions.2. Redirecting Line ID Presentation (RLIP)When an incoming call over the TDM/IP network or a CS 1000 originatedcall which has undergone redirections is directed towards the CAS+compliant system, Redirecting Line ID can be provided over the CAS+interface. This is assuming that the incoming call has the RedirectingLine ID without any presentation restrictions.3. Message waiting indication (MWI)Message waiting indication can be provided over the CAS+ interface.Electrical specificationsTable 112 "LEI card - line interface unit electrical characteristics" (page273) provides a technical summary of the E1 line interface. Table 113 "LEIcard - power required" (page 273) lists the maximum power consumedby the card.E1 channel specificationsTable 112 "LEI card - line interface unit electrical characteristics" (page273) provides specifications for the 30 E1 channels. Each characteristicis set by a dip switch.
