Important Notes

This section contains important information regarding the Cisco IPVC 3540 Serial Gateway Module.

Gateway Security

To ensure that the Cisco IPVC 3540 Serial Gateway Module is secure from outside infiltration, we recommend that you change the default settings of the following options:

•Gateway user name and password

•SNMP service community parameters in the Board section, Basics tab of the Gateway interface.

Interoperability with TANDBERG terminals.

The Cisco IPVC 3540 Serial Gateway Module supports TANDBERG terminals on which software version B3.2 or later is installed.

Inserting an RTM Module into the Cisco IPVC 3544 Chassis

The Cisco IPVC 3540 Serial Gateway Module has two components that you must install in the Cisco IPVC 3544 chassis. These components compliment each other. You must install these components in corresponding slots in the front and at the rear of the Cisco IPVC 3544 chassis.

---

Caution You must install the Rear Transmission Module (RTM) before you install the gateway board. Failure to do this can damage the Cisco IPVC 3544 chassis and render it inoperable.

---

Before you insert the gateway board in the system slot (the top slot) in the front of the Cisco IPVC 3544 chassis, you must first insert the RTM in the top slot at the rear of the Cisco IPVC 3544 chassis.

Before you insert the gateway board in any of the lower three non-system slots in the front of the Cisco IPVC 3544 chassis, you must first insert the RTM in the corresponding slot at the rear of the Cisco IPVC 3544 chassis.

Before you insert the gateway RTM board in the top slot at the rear of the chassis, you must first remove the existing RTM and insert the new RTM.

Procedure

---

Step 1 Remove the rear panel of the Cisco IPVC 3544 chassis covering the slot by loosening the two fastening screws and opening the latches.

Step 2 Unlock the latches at the sides of the board by pulling the latches outwards to the sides.

Step 3 Slowly pull the RTM board halfway out.

Step 4 Detach the flat cable 16-pin connector.

Step 5 Remove the RTM board completely.

Step 6 Take the new RTM board and slide it into the guide railings of the appropriate slot at the rear of the Cisco IPVC 3544 chassis until the RTM board is halfway in.

Step 7 Attach the flat cable 16-pin connector to the socket in the middle of the RTM board.

Step 8 Continue to slide the gateway RTM board into the guide railings of the appropriate slot at the rear of the Cisco IPVC 3544 chassis until the board makes initial contact with the backplane. Make sure not to use unnecessary force.

Step 9 Push the latches in toward the center of the RTM until they lock.

---

Caution Failure to implement this procedure can damage the Cisco IPVC 3544 chassis and render it inoperable.

Resolved Caveats - Release 3.0

The following caveats have been resolved since Cisco IPVC 3540 Serial Gateway Module Release 2.0:

•The transfer of files from the serial side to the IP side using T.120 operates correctly.

•Accurate information appears in the Call Details window when the serial link is down.

•Video channel bit rate data is accurately calculated and displayed in the Call Details window.

•T.120 channel data accurately appears in the Call Details window.

•The T.120 application sharing mechanism is improved.

Known Issues

The following is a known list of issues for the Cisco IPVC 3540 Serial Gateway Module Release 3.0:

•When the gateway IP address is modified in the Addressing tab of the Board section of the Gateway interface, the web browser might stop operating for approximately 50 seconds. To shorten this interval, relaunch your web browser.

•We recommend that you use Microsoft Internet Explorer version 5.0 or later as your web browser.

•The Ethernet port might stop responding if disconnected and then reconnected when there are active calls in the gateway. To restore Ethernet port functionality, reset the gateway.

•Dual Tone Multi-Frequency (DTMF) interpretation problems occur when using the G.723.1 audio channel in gateway-to-Cisco IPVC 35xx MCU voice calls. Use the Force711ForMCU enable advanced command to configure the gateway to open a G.711 channel only. This setting is enabled by default when the gateway is shipped with transcoders. When the gateway has no transcoders or transcoder capabilities are disabled, disable the setting using the Force711ForMCU disable advanced command.

•Modified Ethernet port settings take effect after the next reset.

•When using an H.323 proxy that does not support the G.722.1 audio codec, unselect the Enable G.722.1 check box in the Media Modes section of the Settings tab in the Gateway interface.

•You might experience poor audio quality when working with Aethra endpoints. Improve audio quality by unselecting the Enable G.722 check box in the Media Modes section of the Settings tab in the Gateway interface.

•You might experience poor video quality when working with Aethra endpoints.

•For secure operation, change Administrator passwords using a serial or Telnet connection.

–To access the serial connection, connect the gateway to a PC equipped with a terminal emulation application and access the network configuration menu. When prompted, enter "P" to change the password.

–To access the Telnet connection, click Telnet in the Advanced section of the Settings tab in the Gateway interface. When prompted, enter "P" to change the password.

•Connection problems occur in IP-to-IP calls through two serial gateways using Polycom VSX 700.

•H.264 interoperability issues might occur when working with eConf.

•Interoperability issues might occur when working with a Polycom VSX endpoint on the serial side. To solve this problem, the VSX should be downgraded to version 7.5.1 or upgraded to version 8.0.

•T.120 data collaboration sessions that transfer files of 1 MB or more can have problems.

•If the Ethernet cable to the gateway disconnects while a Telnet session is active, the Telnet session can lock. You must start a new Telnet session to continue.
