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

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.

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

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

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,
log in to the Supervisor and go to Hardware > Blades. To access the web interface of
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.
