Feature Description

DTMF translation The gateway supports translation between in-band Dual Tone

Multi-Frequency (DTM F) sig nal s (on th e ISD N si de) and out- of- band H.245 messages (on the IP side). DTMF translation occurs for voice and video calls.

Dual video The gateway sup ports H.239 standards-based d ual video and TANDBERG

DuoVideo technology. Dual video streams enable a screen to carry video images from one sourc e while simul taneousl y displayi ng images fro m a second source.

Conceal caller ID The gateway supports a conceal caller ID feature that instructs the

gatekeeper to conc eal the id entity of the call ing endp oint on th e IP or ISDN network, whether the presentation restricted feature is enabled or not.

H.323 fast start The gateway H.323 fast start feature enab les endpo ints to jo in a voice

conference in the gateway more quickly.

ISDN rollover (available in Cisco Unified Videoconferencing 35

The gateway features ISDN rollover. In this feature, the gateway sends a “busy out” channel request to the PSTN switch when th e curren t PRI connection is left with less than a predefined number of available B channels. The PSTN switch “rolls over” to the next available gateway.

27 PRI Gateway only) Network Specific

Facility (available in Cisco Unified Videoconferencing 35

The gateway provides support for Network Specific Facility Information Elements (NSF IEs) which enable system administrators to specify to service providers the eq uipment, service, or ne twork throug h which they want a call routed.

27 PRI Gateway only) ISDN connectio n

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 c a ll. D ownspeedi ng c ontr ibutes to a higher percen tag e of c all c om pleti on o n the network. T he ga teway supports downspeeding at call set up and in mid- call.

Multiple trap server

The gateway supports up to three SNMP trap servers.

support H.239 support The gateway supports the H.239 protocol in ISDN-to-IP ca lls and in

IP-to-ISDN ca lls.

Encryption support The gateway supports H.235-compliant AES 128 encryption for calls over

IP networks, and H.233 and H.234 -comp liant AES 128 enc ryptio n 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 . T he ga teway iden tifies t he p roto col version t hat an I P endpoint uses and sends H.239 capabilities only to those endpoints working with protocol version 4.0 or later.

About Gateway Call Bandwidth Overhead

According to the H.320 standard, the available bandwidth allocated to a call at any given bit rate will always be slightly less than the stated maximum for the following reasons:

• All stated maxi mu m ca ll band widt h s inc lude p rovisio n f or cont ro l, audi o, vide o, a nd dat a t raffic.

• Video traffic on the ISDN side contains additional bits for error correction purposes which also

consume bandwid th. Video traffic on the IP side doe s n ot inc lude this addi tiona l l o ad.

• Opening an audio channel further reduces the bandwidth available to the video traffic.

For example, a call at 384 Kbps actually has onl y 363 Kbps available to it. Control and error correction account for the rema ining 21 Kbps.

About Cisco Unified Video conferencing 3500 Ga te way Functionality

Resource Allocation across E1/T1 Lines

The gateway can allocate bandwidth resources to calls across separate E1 or T1 connections to maximize bandwidth capacity in cases where there is not enough capacity for a call on a single E1 or T1 connection, but where sufficient capacity does exist when remaining capacity on both E1/T1 lines is combined.

For example, a gateway using two T1 li nes c an su pport thr ee 6B cal ls on e a ch T 1 li ne, wi th 32 0 Kb ps spare capacity per line:

• Each T1 line provides 23 B channels.

• Each B channel su pport s 6 4 Kb ps

• Each T1 line supports 23 x 64 = 1472 Kbps

• Each 6B call requires 6 x 64 = 384 Kbps

• Each T1 line sup por ts 14 72/38 4 = 3 6B c a lls + 32 0 Kb ps s par e

The gateway processes an additional 6B call requiring a further 384 Kbps by taking bandwidth resources from each of the two T1 lin es, both of which have 320 Kbps available. In this way, the gateway spreads the call over both T1 lines.

Preparing for Installation of the Cisco Unified Videoconferencing3522 BRI Gateway

The Cisco Unified Videoconferencing 3 522 BRI Gateway prepares the signal ing for out bound videoconference calls that are transmitted over Integrated Services Digital Network (ISDN) networks. For videoconference in format ion to arr ive at its destination , you must work with the BRI ser vice provider to ensure that the gateway and the ISDN service are compatible. You must gather information about the service provider equipment and provide the service provider with information about the gateway.

Before you order BRI se rv ice o r c onn ect the Cisc o Unified Videoconferencing 3522 B RI Gateway to your existing BRI service, we suggest that you gather the following information.

Step 1 Ident if y the ISDN provide r you wa nt t o use as your Loc al E xcha nge C ar rier ( LEC) fo r loca l c a lls.

Note The LEC is the loc al telephone co mpan y that prov ides ISDN se rvices for your local ca lling are a

and to which your equipme nt con nects.

Step 2 Ident ify the ISDN provider you want to use as your Interexchange Carrier (IEC) for long-distance calls.

Note The IEC and the LEC are different companies. Often the LEC will contact the IEC and provision

long-distance service for you. V erify that your LEC performs this task, and contact an IEC if the LEC does not.

Step 3 Determine how many BRI lines you want to connect to the gateway. Step 4 Identi f y the ISD N e quipm e nt or sig na ling form a t you r LEC u ses . Step 5 Dete rmin e whe ther y ou wan t to use la yer 1 l ine h unti ng. Step 6 Have your ISDN service provider turn off the following switch settings:

• Packet Mode Data on the D channel

• Terminal Display Text
