TECHNICAL REFERENCE
The MS48IP exchangeis amodularsystem, whichhasIP technologyintegrated,with
bothanalog and IP ports. The system, bywayofits modularand hybridstructure,
supports 4-24 trunks and 12-64 extensions. The systemsupports SIP protocolon the
IP side.
The exchangebasic capacityis 8linesand20 extensionsand can beincreasedto
highcapacitiesbyinstallingexpansion cardsbetween theMS48IP motherboardand
the EXP48IP VoIP card.Besides, thanks toan additionalslotforthe IP expansion,the
system IP channel capacitycan alsobe increased.
EXP48IP VoIP Cardis alsoequipped withthe capabilityofbothreceiving the number
information pertaining tothe calling party(CallerID) on calls comingoverlinesand
distributing thatinformation,aswellasthe numberinformationpertaining tothe calling
extension oninternalcalls, tothe telephonesofthe extensionswiththe CallerID
feature.Thanks tothatcard,the extensionswithSMS-compatible(Short Message
Service) telephones can send and receiveSMS messages over analoglines.
The MS48IP system basicallyconsists of theseparts:
ØCBN48IP Plastic Cabinet
ØSPS48 Power SupplyModule
ØPWT48 Power Transformer
ØRNT48 Ringer Transformer
ØMB48IP Motherboard
ØEXP48 CapacityExpansion Modules
ØEXP48IP VoIP Module
ØVoIP48 DSP Expansion Modules
The basic capacityofthe systemis 4analog trunkand 4IP trunk, 12 analog
extensionsand 8IP extensions, butthatcapacitycan be increased to84 ports intotal
byexpansion modules. Expansion moduleswithdifferentcapacitiesandtechnologies
areavailablefor that:
·The EXP48 (2/6) Module(At most 1of them can be installed.)
·The EXP48 (4/12) Module(At most 2of them can be installed.)
·The EXP48 (0/16) Module(At most 1of them can be installed.)
·VOIP48 4Channel DSP Expansion Module(At most 1of them can be installed.)*
·VOIP48 8Channel DSP Expansion Module(At most 1of them can be installed.)*
*Onlyone DSP expansion modulecan beadd tothesystem.
