AT-VP504E FXS AT-VP504E FXO Voice over IP for LAN and WAN VoIPtalk Telephony Gateways VoIPtalk - Voice over IP Networking for the Enterprise VoIPtalk is Allied Telesyn’s Voice over IP networking solution for the enterprise, scaling from the smallest remote office to the busiest central site. VoIPtalk components include telephone/IP gateways, PSTN/IP gateways and the management software required to control the operation of these networks. VoIPtalk is designed to dramatically reduce telecommunications costs, since calls are re-routed through data networks instead of standard telephone networks. Outlay is minimal as VoIPtalk fully utilises existing telecommunications equipment and IP data networks. VoIPtalk products interwork seamlessly with Allied Telesyn’s comprehensive range of wide area network routers. The AT-VP504E FXS Telephony/IP Gateway The AT-VP504E FXS (Foreign Exchange Service) connects up to four conventional telephones or G3 fax machines to a Local Area Network with access to an intranet or the Internet to permit high-quality, full-duplex, audio/fax communications over IP Networks. Allied Telesyn’s AR series of routers can provide the gateway required to connect to the Internet or corporate IP wide area network (WAN), supporting quality of service (QoS) features designed to ensure optimum voice quality. The AT-VP504E FXS performs all required IP telephony tasks in one compact standalone enclosure. It digitises the audio signal coming from the telephone or fax and then compresses and packetises this for transmission over the TCP/IP network. The AT-VP504E FXO PSTN/IP Gateway The AT-VP504E FXO (Foreign Exchange Office) unit supports up to four analogue connections to the Public Switched Telephone Network (PSTN), providing a PSTN gateway facility for IP networks. A number of PSTN gateways may be installed on an IP network, at different locations. When an IP voice call needs to be ‘broken out’ to the PSTN network, the PSTN gateway nearest the destination can be used. In this way, potentially long-distance calls can be turned into ‘local’ calls and high telco charges can be avoided. Alternatively, incoming calls from the PSTN can be routed through the AT-VP504 FXO for connection to telephones attached to AT-VP504 FXS units on the IP network, ensuring that legacy compatibility is maintained. ‘Hop-on’ and ’hop-off’ PSTN gateways can be used to allow PSTN calls to locally access the corporate IP network, be routed internationally over IP, then break back out through another PSTN gateway at the destination, as a local call. Fully Configurable 'PSTN-Like' Experience The AT-VP504E FXS provides all the usual tones normally heard on the standard telephone network. For example, a dial tone will be heard as soon as the handset is lifted. Call progress tones such as ring-back, busy and error are programmable by country. In addition, the AT-VP504E FXS can be configured to accept virtually any format of telephone number, for example, a series of three digit ‘extensions’ numbers could be set up to make calls, as used on a PBX, or it can be configured to look like the PSTN with users dialing a full ‘national’ number to make a connection. Choice of SIP or H.323 Operation The AT-VP504 units support both Session Initiation Protocol (SIP) as well as the older H.323 protocol for VoIP networks. Newer installations will favour SIP due to its optimisation for IP networking and better response times, while legacy networks may require H.323 operation for interworking and compatibility reasons. SIP or H.323 protocol is an order option. Easy to Set-up The AT-VP504E units can be integrated seamlessly into an existing management environment. SNMP support for SIP units and an integral HTTP server for H.323 operation allows remote management and configuration to be carried out simply and quickly. The units are designed to be desktop stackable. With the optional mounting kit, they can also be wall-mounted or rackmounted. They can be upgraded simply and quickly by loading new firmware into Flash memory using the Trivial File Transfer Protocol (TFTP), new enhancements can be emailed to site then loaded into the unit in a matter of seconds. Application showing long line PBX Extension REMOTE OFFICE CENTRAL OFFICE AT-VP500 SIP Server IP WAN PBX Router AT-VP504E FXS Router AT-VP504E FXS PSTN In this SIP example, central PBX connectivity is extended to remote offices and teleworkers over the IP data network, resulting in PSTN call charge savings. The IP data network can be local or world-wide. All AT-VP504E phone/fax/PBX connections are analogue. The AT-VP500 SIP Server provides call address mapping, user registration and AT-VP504E device configuration.

IP voice calls are converted into analogue form for transmission across standard telephone lines; similarly, incoming calls from the normal telephone network are converted into IP calls for onward transmission across the corporate IP network. This allows local PSTN callers to ‘hop onto’ the corporate IP network and make free long distance calls to corporate or other destinations.

The IP voice call is then routed, free of charge, across the IP network to New York, where it accesses a second PSTN gateway and ‘hops-off’, making a second local call to Phone B. "VoIPtalk offers toll-quality, fully standards based, voice/fax over IP networking for both the small offfice and the enterprise, including gateway services to the public telephone network." Analogue Modem and Fax Interface The AT-VP504E FXS can be used with 9.6kbps to 33.6kbps analogue modems (V.34 support over clear channel). All four ports of the AT-VP504E FXS are capable of handling G3 fax transmissions at speeds up to 14.4kbps. Automatic fax mode detection is standard on all ports, so the unit automatically detects if a call originates from a voice or fax transmission and acts accordingly. Full Integration with Allied Telesyn’s AT-VP500 SIP Server The AT-VP500 SIP Server is a set of software tools that helps manage a network of AT-VP500 products and SIP users to provide end-to-end IP Telephony solutions. In particular, the AT-VP500 SIP Server helps to translate standard telephone numbers into their corresponding IP addresses, looks for available gateways to place calls onto the PSTN and keeps records of all available AT-VP500 devices on the network. The SIP Server runs under Windows NT and is required to make effective use of a network of AT-VP504E FXS/FXO units. H.323 Gatekeeper When operating the H.323 protocol, the AT-VP504E FXS/FXO units require a H.323 Gatekeeper to provide a broad range of network services, including configuring, monitoring and managing registered network users. Policies can be set to control network resources such as bandwidth. The H.323 Gatekeeper also provides address translation, network topology and zone control functions. The H.323 Gatekeeper software runs under Windows NT. Quality of Service (QoS) Support Differentiated Services Code Point tagging (DSCP), or ‘DiffServ’, is supported, this allows a number of different QoS values to be assigned to the voice packets, for example, the default setting is ‘low delay, high throughput and normal reliability’. Corresponding policy filters can then be defined in Allied Telesyn routers to provide for priority voice transmission across the wide area IP network. 802.1q VLAN tagging is supported by the AT-VP504E FXS/FXO in H.323 mode, for Ethernet frame prioritisation. Supplementary Telephony Services The AT-VP504E FXS operating in SIP mode, offers telephone services that a user can use directly on their telephone:• Call forward on unconditional, busy and no answer • Call waiting • Call transfer • Caller ID on call waiting Emergency Bypass In addition to the four phone/fax ports, the AT-VP504E FXS has a fifth RJ11 connector used to connect to a standard PSTN line. During normal operation, this line is not used, however, if mains power should fail, or if the IP network is down, the PSTN line will automatically be switched in and can be used as an emergency bypass line. The bypass line can also be triggered by a software control signal.
