Assign an ISDN-PRI 
Layer 1 to Digital 
Circuit Cards
Note:Before a new protocol can be assigned to a circuit card, any 
existing protocol must first be unassigned. See Unassign T1 A/B 
Robbed-bit E&M to Digital Circuit Cards
 on page 314
 for more 
information.
Before attempting to make any assignment changes to circuit 
cards, they must be in the MANOOS...

To decrease the incoming speech volume, multiply by 0.707 to 
approximately half the value or decrease it by 3 dB.  Therefore, a value of 
707 in the field reduces the volume by half, 500 by half a second time, 
etc. 
See Table 33 on page 338
 for the relationship between the volume 
number and the actual change in volume expressed in decibels.
