SMR-17VS

Submodule SMR-17VS is designed to be installed on the MR-17V module-motherboard, which is a part of the SG-17R universal multiservice platform; is used for setting up FXS interfaces to link up subscriber equipment, namely telephone sets, modems, fax machines.

Description

 Submodule SMR-17VS features 2 FXS interfaces (foreign exchange system) for linking up subscriber lines from PBXs. 

• Ready-to-dial signal
• Voltage for subscriber equipment 
• Dialing signal
• Tone-dialing detector

• Using existing IP-networks for data transmission
• Setting up multipurpose traffic within the chosen data channel
• Managing traffic within the chosen transmission channel, both using QoS and dedicating a fixed band for IP-traffic
• Transmitting data through heterogeneous media, like optics, EM waves, satellite signals, which require data routing at junctions
• ransmitting data over various interfaces (Ethernet, SHDSL, E1, RS232) without additional equipment

• Setting up operation modes for VoIP-modules over web-interface
• Codecs: g711 (aLaw and uLaw) – 64 kbit/s, g723 – 6,4 kbit/s, g729 – 8 kbit/s, g729e, g726 (at 16,24,32 and 40 kbit/s), iLbc (at 13.33 kbit/s)
• T.38 support (for facsimile messages)
• Alteration of transmission-frame, codec identificator in the rtp-stream (payload) and the order of bit-packing (aal2 or rtp) for g726
• Prioritization of codecs
• Independent setup for such channel characteristics as: dtmf transmission type (in-band, out-of-band (rfc2833), both or none), payload when using rfc 2833, volume when signal coding/decoding, activity sensor (VAD), HPF (high-pass filter)
• Determining sip-uri and the registration server for linkup to a remote sip-address during operation time (the coming calls will be redirected to the chosen FXS channel)
• “Hotline” option (for FXS channel it means that the call we directed to the chosen address the second the telephone handset is lifted; for FXO channel it will mean redirecting the call from PBX)
• Telephone book
