Jumper Locations Figure 1-13shows the location of jumpers on the DSPM/SM card that terminate the Multi-Vendor Integration Protocol clock.

Installing Jumpers Figure 1-13shows how to install the jumpers on the DSPM/SM card to terminate the Multi-Vendor Integration Protocol clock.

The DSPM/SM card with the jumpers set to the installed position must be located furthest from the T1 or E1 card as shown in Figure 1-14(the T1/E1 card is always located in slot 8). All other DSPM/SM cards must have their jumpers in the “not installed” position.
