T ANDBERG Gateway 7 Introduction Introduction The T ANDBERG Gateway enables sites on IP and sites on ISDN to p articipate in meetings with each other with the quality and reliability found in all T ANDBERG equipment. IP Services and Procedures • Service Prefix.
8 T ANDBERG Gateway Video Quality • Natural Video TF which provides 60 fields per second true interlaced picture. • H.264, H.263 and H.261 video compression. Presentations Allows to watch a presenter on one video channel and simultaneously a second video channel (live presentation, document camera and others).
T ANDBERG Gateway 9 Management Interfaces SOAP Simple Object Access Protocol is a lightweight protocol for exchange of information in a decentralized, distributed environment X M L Extensible Markup Language is a flexible way to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere.
10 T ANDBERG Gateway Introduction Front view The front of the gateway contains 24 Light Emitting Diodes (LEDs) organized in three groups. These diodes provide information about PRI-line status, LAN (Ethernet) connection and power .
T ANDBERG Gateway 11 Introduction Rear view The back panel provides four PRI interfaces, two LAN interfaces and one RS 232 interface located together with the power switch/connector and four cooling fans.
12 T ANDBERG Gateway Installation Precautions • Never install telephone wiring during a lightning storm. • Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. • Never touch uninstalled telephone wires or terminals unless the telephone line has been disconnected at the network interface.
T ANDBERG Gateway 13 Installation Inst allation site prep arations • Make sure that the gateway is accessible and that all cables can be easily connected. • For ventilation: Leave a space of at least 10cm (4 inches) behind the gateway’s rear panel and 10cm (4 inches) in front of the front panel.
14 T ANDBERG Gateway Installation Connecting cables Power cable Connect the system power cable to an electrical distribution socket. ISDN PRI cables For each of the four PRI interfaces, the E1/T1 cable should be connected to a CSU (Channel Service Unit).
T ANDBERG Gateway 15 Installation Gateway Configuration The gateway requires some basic configurations before it can be used. It will be necessary to find the IP-address and program the ISDN-PRI Line numbers. T o do this configuration, follow the instructions below: 1.
16 T ANDBERG Gateway Installation GW Accessing the gateway Y ou may access the gateway by entering the IP-address of the gateway in a standard WEB-browser . Y ou will then be asked to enter a password. It is not necessary to enter ‘User Name’. The default password for the gateway is ‘ T ANDBERG ’.
T ANDBERG Gateway 17 Installation Using the Gateway The following Web-page, called ‘ Overview ’ will be shown when the correct password has been entered and shows all calls currently active through the gateway . Call Overview GW Calls Shows each active call through the gateway .
18 T ANDBERG Gateway Using the Gateway E NABLING ENCRYPTION WILL REDUCE THE CAP ACITY OF THE GA TEW A Y . NOTE Source / Destination Source shows the S tatus of the incoming call to the gateway , the number and which network the incoming call is using.
T ANDBERG Gateway 19 Using the Gateway Actions When a call is active, the Administrator or Operator has the possibility to disconnect the call, or transfer the call from one IP endpoint to another . Disconnect Gateway Call Will disconnect the selected gateway call.
20 T ANDBERG Gateway Using the Gateway Usage The usage bar shows the current status of all the available resources (CPU, ISDN channels and number of calls) When the Resource Usage reaches the “Busy on Load”-limit, the gateway will try to route outgoing IP calls to other gateways.
T ANDBERG Gateway 21 Dial from ISDN Dial from ISDN The gateway supports four different ISDN Dial In services: • IVR • IVR + TCS4 • DID • Hotline Any of these services can be enabled or disabled, but at least one must be enabled for incoming call routing to take place.
22 T ANDBERG Gateway Dial from ISDN IVR + TCS-4 IVR + T erminal Control Session 4 (TCS-4) is an extention dial-in method that combines IVR with TCS-4. In this mode the extention number can be indicated with IVR (see above) or TCS-4 signaling.
T ANDBERG Gateway 23 Dial from ISDN • The gateway starts to call the IP endpoint and the “Call proceeding” picture and sound are activated. • When the call is connected audio and video are transmitted through the gateway .
24 T ANDBERG Gateway Dial from IP Dial from IP IP endpoints and MCUs can call out through the gateway by using one of the H.323 services defined on the gateway . H.323 Services H.323 Service prefixes are used for IP endpoints to access the ISDN network.
T ANDBERG Gateway 25 Features Dial out to 2x64k ISDN (H.221) For improved interoperability with legacy equipment, the two number 2x64k dial-out method can be selected from the calling IP endpoint instead of using the standard BONDING method.
26 T ANDBERG Gateway Features Bridging IP Islands Organizations that uses IP based video conferencing internally in their LAN but not for external purposes can be called “IP Islands”. If a user in one IP island wants to call another user in another IP island, both organizations have to be connected with a Gateway .
T ANDBERG Gateway 27 Manage the Phone Book The Expressway Solution IP based video conferencing between organizations has been hindered by two major barriers: · Firewalls which block audio and video traffic. · Lack of a common dial plan for IP based video conferencing.
28 T ANDBERG Gateway Features In a typical enterprise setup, such as the one in the previous figure, the Gateway is registered with a Gatekeeper , and the Gatekeeper is registered with the Border Controller .
T ANDBERG Gateway 29 Features Manage the Phone Book By selecting the ‘ Phone Book ’ tab, you can add new or edit existing Phone Book entries in the gateway . The Phone Book can be used when Transferring calls from one IP endpoint to another and can contain up to 99 single entries.
30 T ANDBERG Gateway Manage the Phone Book Edit Entry By selecting an existing Entry in the Phone Book and then pressing the ‘ Edit ’ button, you will be able to edit the selected entry . The same fields as for the ‘ Add New Entry ’ will be available.

52 T ANDBERG Gateway Configure the Gateway Calls above the Dial In Max. Bandwidth will be downspeeded to the call rate specified in Dial In Max. Bandwidth. Calls below the Dial In Max. Bandwidth will be connected at the requested call rate. Dial In Number All incoming calls received on this number will use the IVR/TCS-4 service.
T ANDBERG Gateway 53 Configure the Gateway Calls above the Max. Bandwidth will be downspeeded to the call rate specified in Max. Bandwidth. Calls below the Max. Bandwidth will be connected at the requested call rate. Direct Inwards Dialing When DID is enabled, all incoming calls within the PRI number range will be forwarded to an IP/H.
54 T ANDBERG Gateway Configure the Gateway H.323 Services H.323 Service prefixes are used for IP endpoints to access the ISDN network. Up to twenty prefixes can be defined, but we recommend using one single prefix for simplicity . Default H.323 Services are ‘0’ for Video calls and ‘1’ for T elephone calls.
T ANDBERG Gateway 55 Configure the Gateway Max. Rate The call rate for outgoing calls will automatically be determined by the call rate used by the endpoint.
56 T ANDBERG Gateway Configure the Gateway Signal Busy on Load When the Resource Usage reaches the “Busy on Load”-limit, the gateway will try to route outgoing IP/H.323 calls to other gateways. This is done to maintain availability for incoming ISDN calls when using multiple gateways.
T ANDBERG Gateway 57 Configure the Gateway Gateway Features Experience has shown that some features - even though they are standardized - might cause interoperability problems with legacy video conferencing products. If you disable features on this page, the gateway can be used as a filter to ensure interoperability with legacy products.
