The Cisco 6110
Each LIM can support four subscriber lines for a total of 80 subscriber lines per chassis. Electronically, the Cisco 6100 with NI-1 system can support up to five Cisco 6110 chassis, for a total of 400 lines.
Data is routed into the Cisco 6110 through two 68-pin connectors (J25 and J26). Data is routed out of the Cisco 6110 through two 68-pin connectors (J27 and J28). Each successive Cisco 6110 is cabled to the previous Cisco 6110 in a chained fashion using the 68-pin connectors.
This chapter covers the following sections:
The module compartment includes 22 slots, and Table 4-1 describes each module slot assignment for the Cisco 6110.
| Module Slot | Module Assignment |
|---|---|
1 to 10 | LIMs only |
11 | LIM controller module |
12 | |
13 to 22 | LIMs only |
| 1Blank faceplates must be installed in all open slots of each chassis. |
 |
Note You can purchase blank faceplates for empty Cisco 6110 module slots. |
Figure 4-1 identifies the Cisco 6110 module slots. Each slot on a chassis is numbered along the top of the chassis. In this guide, the slot numbers are shown on the modules for easy reference and readability. These slots are referred to in subsequent sections of this chapter and elsewhere in this guide.
|
Note A Cisco 6110 can be used only in a DOH configuration. The physical pool A and physical pool B callouts in Figure 4-1 apply only in a DOH configuration. |
Figure 4-2 shows the Cisco 6110 backplane.
Table 4-2 describes the connectors on the backplane of the Cisco 6110.
This section contains the following information about the types of Cisco 6110 modules:
The LIMs provide intraoffice protection, DOH detection, line concentration, and switching circuitry.
|
Note Make sure each network element has protection from electrical problems due to major electrical events (for example, lightning). |
Each LIM is equipped with
Use LIMs when it is necessary to oversubscribe (or concentrate) lines to CAP ATU-C ports in the Cisco 6100.
LIMs are associated with physical modem pools A and B in the Cisco 6100.
|
Note In the Cisco 6100 with NI-1 system operation, there is a distinction between physical and logical pools. For more information, refer to the ViewRunner for Windows Digital Off-Hook Provisioning and Operation Guide or the ViewRunner for HP OpenView Digital Off-Hook Provisioning and Operation Guide. |
Figure 4-3 shows a close-up of the LIM faceplate.
Table 4-3 describes the LIM LED indicator functions.
| LED | State | Function |
|---|---|---|
STATUS | Green blinking | The self-test is in progress. |
LINE 1 | Green blinking | The LIM port is detecting DOH but is not configured with a subscriber or the configured subscriber is locked. |
LINE 2 | Green blinking | The LIM port is detecting DOH but is not configured with a subscriber or the configured subscriber is locked. |
LINE 3 | Green blinking | The LIM port is detecting DOH but is not configured with a subscriber or the configured subscriber is locked. |
LINE 4 | Green blinking | The LIM port is detecting DOH but is not configured with a subscriber or the configured subscriber is locked. |
The LIM controller module
Figure 4-4 shows a close-up of the LIM controller module faceplate.
Table 4-4 describes the LIM controller module LED indicator functions.
| LED | State | Function |
|---|---|---|
STATUS | Green blinking | The self-test is in progress. |
ACTIVE | Green solid | The module is activated (not on standby). |
