Supports the TTC JJ-20.10-12 standard with a line rate of 2.048 Mbps

Single Network Module VIC-1J1思科原装线卡模块scales using from one to five 12-channel packet voice DSP module (PVDM-12) upgrade SIMMs to support from 1 to 30 voice channels.

Standards-based ITU-T G.711 PCM VIC-1J1思科原装线卡模块encoding provides 64 kbps analog to digital conversion using u-law or A-law.

Users can choose to either transmit voice across their networks as uncompressed PCM (G.711, u-law and A-law) or compressed from 5.3 kbps to 32 kbps using standards-based compression algorithms (G.729, G.729a/b, G.723.1, G.726, G.728).VIC-1J1思科原装线卡模块

Transmit Group III fax and T.38 over any voice channel without sacrificing voice processing resources regardless of compression type.VIC-1J1思科原装线卡模块

Transmit voice across a single frame relay, ATM, ISDN, channelized, or multilink point-to-point protocol (MLPPP) network.VIC-1J1思科原装线卡模块

Leverage existing or new frame relay network by transporting voice directly over this network using standards based transport methods (FRF.11). VoIP can also be transmitted over Frame Relay.

Transport voice directly over ATM networks using AAL 5 encapsulation. Leverages existing ATM networks as a direct transport method for voice. VoIP can also be transported over ATM (VoATM requires ATM network modules such as IMA or OC-3).VIC-1J1思科原装线卡模块

Creates a tie-line replacement structure while only consuming bandwidth during a call.

Reduce or eliminate toll charges assessed by long distance and local carriers by transporting voice and fax traffic across the enterprise intranet, LAN, metropolitan-area network (MAN), or WAN. Businesses incur significant recurring monthly costs for leased lines purely for the interconnection of telecom PBXs and switches. This product gives these enterprises the ability to remove these costly rigid-bandwidth leased lines and replace them with flexible bandwidth lines. The ability to support proprietary PBX signaling types exists by using connection trunking and transparent CCS.VIC-1J1思科原装线卡模块

Automatically busy out any desired voice trunk line (or individual DS0s) to a PBX when a direct WAN or LAN connection to the router is down. Also, busy out a far end trunk connection when configured for Connection Trunk. AVBO adds the capability to busy out voice trunk lines triggered by Security Assurance Agent (SAA) probes.

Supports three types of loopback modes - line and local loopback, and isolation.

Supports clear channel transparent common channel signaling

Supports J1 channel associated signaling VIC-1J1思科原装线卡模块

Uses industry-standard signaling protocols for call setup between gateways, gatekeepers, and H.323 end points. Enables comprehensive, flexible application configuration for voice over IP, desktop video conferencing, collaborative computing and electronic whiteboard applications.VIC-1J1思科原装线卡模块

Carries DTMF tones/information out-of-band for clearer transmission and detection.

Interoperates with Cisco IP phones, analog phones, fax machine connections, and PBX connections to and from any other Cisco voice enabled product. VIC-1J1思科原装线卡模块

Interoperable within Cisco's AVVID IP Telephony architecture (H.323 Networks)

Supports H.323 call control protocols. VIC-1J1思科原装线卡模块

Enables a connection for incoming and outgoing calls to Japanese PBXs using Cisco IP phones, fax machines and other key communnication systems connected to a data, voice and video infrastruc
