IP/Ethernet Connections

Processing Functions

Hot-swap capable dual-redundant internal auto-ranging power supplies. 90 – 132 / 187 – 264 VAC, 50Hz/60Hz. IEC receptacle, internal fuse.
Power consumption: 100 Watts

Operating Temperatures

Via Livewire IP/Ethernet. Each channel (hybrid) has one input and one output
Each studio has a Program-on-Hold input
Each Acoustic Echo Canceller has two inputs (signal and reference) and one output
Livewire+™ AES67 equipped studios may take and supply audio directly to/from the network. Telos Alliance xNodes are available for analog and AES3 breakout.
VX supports AES67 connectivity. AES67 stream parameters:
(2) channels per stream, 1 ms packetization rate
Sample rate: 48 kHz
Payload type: 46
Source port: 5001
Destination port: configurable
Time to live (TTL): configurable (1-255)
IEEE 802.1p priority code point (PCP): configurable (0-7)
IEEE 802.1Q VLAN tag: configurable (0-4094)
DiffServ code point (DSCP): configurable (0-63)
Don’t Frag (DF) bit: configurable (true/false)
Receive buffer size: configurable (2000-20000 μs)
VX supports PTPv2 (IEEE 1588-2008) clocking. Domain, sync interval, announce interval, announce timeout, and many other parameters are all configurable.

Audio: standard RTP. Codecs: g.711μ-Law and A-Law, and G.722.
Control: standard SIP endpoint. ISDN PRI/T-1, ISDN BRI, and POTS may be supported with the appropriate interfaces using an existing PBX or an Asterisk-based PBX optionally configured by Telos Alliance.
