General information

About the Cisco TelePresence ISDN GW MSE 8321

The Cisco TelePresence ISDN GW MSE 8321 (ISDN GW MSE 8321) is a high

performance video gateway which enables ISDN network connectivity for the Cisco

TelePresence IP-based video infrastructure products as well as IP-based endpoints.

green

One of:

the ISDN GW MSE 8321 is booting

a configuration change has been made

the configuration is being transferred by FTP

Status Green The ISDN gateway is operating normally

Alarm Red The ISDN gateway is booting or has developed a

fault, for example:

temperature is outside normal limits

battery failure of the internal clock

Refer to the web interface for more information

about the problem (go to Status > Health)

ISDN Port Status, for each ISDN port:

L1 Off There is no connection on this port, or the ISDN

gateway is not receiving framing (also known as

Red Alarm)

Flashing

green

The ISDN gateway is receiving framing, but the far

end is not receiving framing (also known as Yellow

Alarm)

Green The port is connected to the far end

L2 Green Layer 2 connectivity has been achieved with the

ISDN network from this port. This means that

D-channel signaling has been established with the

network

Act Green There is at least one active call using this port.

Data is currently being received on this port

General information

Ethernet Port Status, for each Ethernet port:

FDX Green The link has been negotiated as a full-duplex link

Act Green Packets are being transmitted on this port

Link Green The speed of the link from this port, which is

either 10, 100, or 1000 Mbps

Power Blue The ISDN gateway is receiving power from the

MSE 8000 chassis

Installing the ISDN gateway

For information about powering the MSE 8000, refer to the Getting Started Guide on

http://www.tandberg.com/support/video-conferencing-documentation.jsp).

Step one: Install the ISDN gateway into the MSE 8000 chassis

1 Remove the blade or blanking blade from the slot into which you are going to

install the ISDN gateway:

i Using a No.1 Phillips screwdriver, loosen the screws in the retaining latches

with an anti-clockwise quarter turn.

ii Open both retaining latches on the front of the blade or blanking blade.

When open, a retaining latch is at a 90° angle perpendicular to the front of

the blade.

iii Slide out the blade or blanking blade.

2 Open both retaining latches on the front of the ISDN gateway. When open, a

retaining latch is at a 90° angle perpendicular to the front of the blade.

3 Slide the ISDN gateway into the blade slot (as shown in Figure 2) until it stops.

IMPORTANT: Before installing the ISDN GW MSE 8321 into the MSE

8000, and connecting the power supply, you must read the safety

information at

http://www.cisco.com/go/telepresence/safety.

Although blades are hot-swappable parts, you must only remove one

blade at any time. Remove the power from the MSE 8000, if you need to

remove more than one blade at a time.

Before hot-swapping a blade, shut down the blade using the web

interface. Do not shut down a blade during a software upgrade or if the

blade is processing.

You must install either a blade or a blanking blade in each of the ten

positions in the chassis.

The Supervisor blade must be installed into slot 1 of the MSE 8000

chassis.

Installing the ISDN gateway

4 Simultaneously close both retaining latches on the blade (thereby engaging the

connectors at the rear of the blade) to secure it in the chassis as shown in

Figure 3.

5 Using a No.1 Phillips screwdriver, tighten the screws in the retaining latches

with a clockwise quarter turn.

Connecting the ISDN gateway

Your ISDN connection

Outside North America

Check with your network provider to ensure that your incoming ISDN PRI line is

terminated in an NTU/CSU (Network Termination Unit/ Channel Service Unit). If

it is not, then seek their advice regarding the provisioning of such a device. Do not

connect the ISDN gateway directly to an external ISDN line.

Within North America

If your network provider has not terminated all of your incoming ISDN PRI lines

with an NTU/CSU, Cisco recommends that you install a suitably approved CSU to

protect the ISDN gateway from damage by surges on your ISDN PRI lines.

Step one: Connect to Ethernet Port A

Connect an Ethernet cable from Ethernet Port A to an Ethernet switch (rather than a

hub, to minimize interference from other devices on the network). The Ethernet

port is a 10/100/1000 Mbps auto-sensing connection.

Step two: Connect to the ISDN ports

The ISDN gateway uses a standard RJ48C ISDN interface for each PRI port. Use a

single straight-through STP patch cable to connect each PRI port on the ISDN

gateway to your ISDN connection.

For information about the behavior of the ISDN port LEDs, refer to Table 1, ISDN

gateway LED behavior, on page 4.

To reduce the risk of fire, use only 26 AWG or larger telecommunication

line cord.

Only connect to Ethernet Port A, as all initial configuration must be done

on this port. Do not connect anything to Ethernet Port B.

For D-channel signaling to be established, the ISDN gateway must have

found and synchronized with the ISDN network clock. In some

installations, you may have to explicitly request your ISDN provider to

enable the network clock before the link will be established.

Initial configuration

Step one: Configure Ethernet Port A settings

The default setting for the ISDN gateway Ethernet ports is auto-sensing mode. If the

switch ports to which you connect the ISDN gateway are not also set to auto-sensing

mode, then you need to configure the ISDN gateway Ethernet ports to use the same

speed and duplex mode.

To configure Ethernet Port A, log in to the Supervisor’s web interface and go to

Hardware > Blades. For more information about configuring the port, refer to the

online help accessible from the Supervisor’s web interface.

Step two: Assign an IP address to the ISDN gateway

You can use the Supervisor’s web interface to configure the IP addresses of all blades

installed in the MSE 8000. Note that all blades are supplied with DHCP enabled. You

can either keep this setting or assign static IP addresses to a blade from the

Supervisor’s web interface. To view or configure the IP address of the ISDN gateway,

the ISDN gateway, go to Hardware > Blades and click the IP address of that blade.

Only connect to Ethernet Port A, as all initial configuration must be done

on this port. Do not connect anything to Ethernet Port B.

Both ends of the Ethernet connection must be configured in the same

way. For example, either configure both ends of the link to be auto-

sensing or configure both ends to operate at the same speed and duplex.

To establish a 1000Mbps connection, both ends of the link must be

configured as auto-sensing.
