Connecting the Terminal
Basic Hardware Features
Basic configuration of your Cisco 8110 unit can be performed in one of two ways: either by using a
standard ASCII terminal, or using the in-band management software application.
To connect an ASCII terminal to the Cisco 8110 terminal port:
Step 1 Configure the terminal: 9600 baud, 8 data bits, 1 stop bit, no parity, xon/xoff flow control.
Step 2 Plug the included console cable into the terminal port located at the back of the Cisco 8110 unit (CIT).
(See Figure 3-1).
Step 3 Connect the other end of the cable to the terminal.
Note Refer to Configuration in Chapter 4 for information on using the console management
software for basic configuration.
To connect the terminal using the in-band management software application, see the“Installing a Line
Interface / Compact Subscriber Module (LIM)” section on page 3-4.

management application.
Step 2 Place the module’s card edges into the right and left module guides at the front of the
Cisco 8110
Step 3 Slide in the module until it makes contact with the backplane, then push firmly to mate the connectors
solidly with the backplane.
Step 4 When the module is seated solidly against the backplane, secure the module’s front panel to the Cisco
8110 chassis using the mounting screws on the right and left of the module’s front panel.
Step 5 Securely install and fasten each module to facilitate the installation of the one next to it.
Step 6 Configure the module type to the actual LIM type, using the console or the in-band management
application.
Step 7 Change the module state to Active, using the console or the in-band management application.

Removing a Line Interface / Compact Subscriber Module (LIM)
To remove a LIM in your Cisco 8110:
Step 1 Change the module state to OOS (Out of Service) using the console, or the in-band management
application
Step 2 Unscrew the right and left mounting screws on the front panel of the module.
Step 3 Remove the module by pulling evenly its mounting screws.
Step 4 Use faceplate panels to protect unused slots from dust and reduce electromagnetic radiation.
Caution If you store modules outside the Cisco 8110 for an extended length of time, place them in
the original packaging (or equivalent packaging providing ESD protection).
Replacing Modules
Basic Hardware Features
Caution All modules are susceptible to electrostatic discharge (ESD) even while installed. Take the
necessary precautions to minimize electrostatic damage while handling modules.
When changing from one type of LIM to another (e.g. from STM-1 to E3) use the following procedure:
Step 1 Change the module state to OOS (Out of Service) by using the console or the in-band management
application.
Step 2 Remove the module
Step 3 Insert the new LIM
Step 4 Change the LIM module type by using the console or the in-band management application.
Step 5 Change the module state to Active by using the console or the in-band management application
Step 6 Reboot the Cisco 8110.
Connecting the External Timing
Timing for the Cisco 8110 can be provided by an external 2048 Kbps signal. The Cisco 8110 outputs the
timing signal, after it has been reconditioned, through its timing output. The timing signal from the Cisco
8110 can be used to synchronize other equipment, including other Cisco 8110 devices.
To connect your Cisco 8110 external timing signals:
78-11666-01
Step 1 Prepare a pair of appropriate coaxial cables with appropriate connectors on the Cisco 8110 side.
Step 2 You may want to mark the ends of the cable so you can identify the wires.
Step 3 Attach one cable into the ETS IN port on the rear panel of your Cisco 8110 unit.

Step 4 Attach the other end of the cable connected to the IN connector, to the timing source.
Step 5 If required, attach the other cable into the ETS OUT port on rear panel of the Cisco 8110 unit.
Step 6 Attach the other end of the cable connected to the OUT connector, to the input of the next equipment
requiring external timing.
Step 7 Set timing source to External timing.
Connecting the External alarms
The Cisco 8110 provides one external dry relay alarm indication, and four external alarm input
indications.
To connect your Cisco 8110 external alarm signals:
Step 1 Prepare a shielded cable with connector plug DB15 with shielded backshell.
Step 2 Attach the D-type connector to the ALARMS port on the rear panel of your Cisco 8110 unit. To secure,
tighten the screws on both sides of the connector.
