3.3.10 Multi-rate WAN Line Card and WICs
This section describes the procedure for installing the Multi-rate WAN line-card. Additionally, if your configuration
uses either a Clear Channel T3 or E3 WIC, you must consider the setting of the WIC module’s grounding-jumpers.
Setting Jumpers on the Clear Channel T3/E3 WICs
Both the Clear Channel T3 and E3 WICs contain a set of jumpers (JP2, JP3,and JP4). These jumpers allow you to set
whether the shielding of the transmit (Tx) and Receive (Rx) cables are grounded. In their default positions, the jumpers
are set such that the shielding on the Tx cable is grounded at the RS and the shielding on the Rx cable is not grounded
at the RS (see Table 3-6 and Figure 3-13).
To ground the shielding on the Rx cableRemove the jumper block on JP4 and place it on the pins of JP3.
Note
The industry standard for E3 is both Tx and Rx cable shielding grounded. To be
E3 industry-compliant, the jumper block must be moved from JP4 to JP3.
To remove grounding of the shielding on the Tx cable – Remove the jumper block on JP2.
