PRODUCTS
SCOPIA Gateway series consists of the following products:
Gateway P20 SP (see About the Gateway P20 SP)
Gateway S40 SP (see About the Gateway S40 SP)
ABOUT THE
GATEWAY P20 SP The Gateway P20 SP enables audio, video, and data communication between
H.320 endpoints that connect through ISDN, and H.323 endpoints that connect
through a packet-based network. For voice over IP, the Gateway enables PSTN
voice callers to connect from the ISDN network to IP voice callers. The
Gateway P20 SP supports two PRI ISDN ports.
ABOUT THE
GATEWAY S40 SP The Gateway S40 SP supports multimedia conferencing over IP by translating
between H.323 and serial protocols. With the help of a V.35 Adtran Imux, the
Gateway can also translate between H.323 and H.320 protocols.
The Gateway offers a serial leg for multimedia conferencing over IP by
providing an interface for legacy endpoints with serial interfaces,
encryption/decryption devices, satellite networks and leased line services.

About Gateway Features
ABOUT GATEWAY
FEATURES Table 1-1 lists the major features of the SCOPIA Gateway.
Table 1-1 Gateway Feature Summary
Feature Description
Interoperability The Gateway provides a high degree of interoperability with other H.323 compliant
gateways, gatekeepers, terminals, proxy, and Multipoint Control Unit (MCU) products by
being based on the H.320 standard and H.323 protocol stack.
Web-based management The Gateway features the Gateway interface. This is a web interface used to configure and
monitor the Gateway. You can view and modify all aspects of the Gateway configuration
from a remote location using a Java-enabled web browser.
SNMP management The Gateway features Simple Network Management Protocol (SNMP) management that
supports all aspects of monitoring, diagnostics, configuration, and trapping.
Diagnostics The Gateway features front and rear panel LED indicators that display status for the unit.
You can also access remote diagnostics of the unit through the Gateway interface, Telnet,
SNMP, or a serial port.
Network load balancing The Gateway supports load balancing on the network by communicating with a gatekeeper
through H.323 RAI (Resource Available Indication)/RAC (Resource Available
Confirmation) messages.
T.120 data collaboration The Gateway supports data transfers in calls between ISDN and IP by using high speed
T.120 in HMLP and VarMLP formats.
Quality of service (QoS) The Gateway features configurable coding of media packets to achieve QoS routing priority
on the Internet Protocol (IP) network. The Type of Service (ToS) bits of the IP datagram
header can be configured for priority level.
Dial plan The Gateway supports a simplified dial plan for outbound dialing using a single universal
prefix. Using the dial plan,the Gateway automatically detects the capabilities received in the
Setup message from the IP endpoint and sets the same bit rate for the ISDN (or serial
interface) side of the call.

Functionality 3
About Gateway Features
Direct dialing and call routing The Gateway dial plan supports the following direct dialing and call routing facilities:
Direct Inward Dialing (DID)
Multiple Subscriber Network (MSN)
Q.931 Sub-addressing Information Element
Gateway S40 SP supports DID in DCE mode only.
Internal and External Interactive Voice Response (IVR)
TCS4
Default extension
Access control The Gateway features password-controlled access to the Gateway interface. Up to ten
different administrator access profiles can be defined for the Gateway.
DTMF translation The Gateway supports translation between in-band Dual Tone Multi-Frequency (DTMF)
signals (on the ISDN side) and out-of-band H.245 messages (on the IP side). DTMF
translation occurs for voice and video calls.
Dual video The Gateway supports H.239 standard-based dual video and TANDBERG DuoVideo™
technology. Dual video streams enable a screen to carry video images from one source while
simultaneously displaying images from a second source.
Hot swap The Gateway features hot swap functionality that you can use to remove and replace
Gateway blades under power.
Conceal caller ID The Gateway supports a conceal caller ID feature that instructs the gatekeeper to conceal the
identity of the calling endpoint on the IP or ISDN network, whether the presentation
restricted feature is enabled or not.
H.323 fast start The Gateway H.323 fast start feature enables endpoints to join a voice conference in the
Gateway more quickly.
ISDN rollover (available in
Gateway P20 SP only) The Gateway features ISDN rollover. In this feature, the Gateway sends a “busy out” channel request to the PSTN switch when the current PRI connection is left with less than a
predefined number of available B channels. The PSTN switch “rolls over” to the next
available gateway.
Network Specific Facility
(availableinGateway P20 SP
only)
The Gateway provides support for Network Specific Facility Information Elements (NSF
IEs) which enable system administrators to specify to service providers the equipment,
service, or network through which they want a call routed.
Table 1-1 Gateway Feature Summary (continued)
Feature Description

4 SCOPIA 400/1000 Gateway User Guide
About Gateway Features
Table 1-2 lists features for specific RADVISION Gateways.
ISDN connection failure The Gateway responds to ISDN connection failure events, by unregistering from its
gatekeeper. The gatekeeper is forced to send new IP-to-ISDN calls through a different
gateway, thus ensuring high call completion rates. The Gateway re-registers to the
gatekeeper when the ISDN connection is restored.
Downspeeding The Gateway features downspeeding functionality. In the downspeeding feature, the
Gateway attempts to reconnect a disconnected video call either at a lower bandwidth or as a
voice call. Downspeeding contributes to a higher percentage of call completion on the
network. The Gateway supports downspeeding at call setup and in mid-call.
Multiple trap server support The Gateway supports up to three SNMP trap servers.
H.239 support The Gateway supports the H.239 protocol in ISDN-to-IP calls and in IP-to-ISDN calls.
Encryption support The Gateway supports H.235-compliant AES 128 encryption for calls over IP networks, and
H.233 and H.234-compliant AES 128 encryption for calls over ISDN networks.
H.243 Conference Control
support The Gateway supports the H.243 protocol in ISDN-to-IP calls and in IP-to-ISDN calls. The Gateway identifies the protocol version that an IP endpoint uses and sends H.239
capabilities only to those endpoints working with protocol version 4.0 or later.
Peer-to-peer connectivity The Gateway supports connectivity to the IP network through a gatekeeper, or directly to a
peer device such as Cisco Unified Communications Manager.
IP network connections The Gateway has one 10/100Base-T Ethernet IP port (on the front panel) and connects to an
IP segment through a direct connection to a network switch.

ABOUT MULTIPOINT
CONFERENCING Together with the RADVISION MCU, the RADVISION PRI Gateway enables
H.320 ISDN terminals to participate in a mixed ISDN-IP multipoint multimedia
conference with IP network endpoints (see Figure 1-3).
For example, when an H.320 ISDN terminal wants to participate in a multipoint
conference with H.323 IP endpoints, the H.320 ISDN terminal can either join
the multipoint conference by dialing to the Gateway, or be invited into the
conference by one of the participating IP endpoints. In either case, the Gateway
connects the ISDN terminal to the RADVISION MCU, enabling it to participate
in the multipoint conference.
