Ground Connections
This section provides the grounding rule for the VC-2402. All remote system sites
must be properly grounded for optimum system performance.
In Central Ofce:
There should be a CO GND that is adequately grounded. If the measured
resistance from the grounding screw (on the front panel of the DSLAM) to CO GND
is less than 5 Ohm, then it can be assumed that the system is well grounded. If
the measured resistance is larger than 5 Ohm, it is recommended to connect the
grounding screw to CO GND using #14 or #12 AWG wire gauge conductor.
In Remote Cabinet:
The VC-2402 should be grounded by connecting a #14 or #12 AWG conductor
between the grounding screw (on the front panel of the DSLAM) and the earth
ground or main grounding bar. The resistance between the chassis and the
grounding bar should be less than 25 Ohm.

1.2.5 Connecting the VDSL/ADSLx and POTS interfaces
The VC-2402 supports 24 ports VDSL2/ADSLx subscribers per box. Depending on
your box, there maybe two RJ21 50-pin female connectors on the front panel of
the system. One for VDSL/ADSLx line and the other for POTS interface.
To connect the subscriber lines, use cables with the RJ21 50-pin male connectors.
When installing, just plug the end of a cable with connector into the POTS or
LINE interface female connector on the front panel. The other end of the cable is
generally tied to the MDF.

POTS port 24 fl 1
LINE port 24 fl 1
The pin assignment of Line/POTS interface is illustrated below (the numbers in
the connector below represent PIN numbers). Please be aware of the different
style pin-assignment.

- The hk circuit contains a photo coupler powered by the vc 2402 to detect the open or close status of the loop between hk_in and hk_com user does not need to feed 3 v power into the circuit as to the alarm output there is a relay between almout and almcom to control the status of the loop to be open or close to the alarm equipment close between almout and almcom for alarm open if no alarm 17
- The pin assignment of housekeeping and alarm contact output interface is illustrated below 17
- The vc 2402 has an rj 50 port hk on the front panel to provide four housekeeping inputs and one alarm contact output generally housekeeping contacts can connect to environment sensor controlled switch to indicate the operation environment condition 17

- In the pc terminal screen type in the login user name and password to login the system type the following cli command to check current ip setting of all the management ports 19
- Restrict incoming vlan tag of in band management this setting is optional not mandatory 19
- Then type the following commands to change in band or out band ip settings as you want 19
- After setting the in band out band ip of the vc 2402 remember to connect its ethernet port mgmt to the ethernet lan then in the previous pc terminal screen type the following command to verify if the ethernet connection between the management station and the dslam is working 20
- B enter new ip setting in the gbe in band sectionforin bandipconfiguration 20
