Chapter 2. Installation

Slots 3-5

Slots 3-5 will accept any interface type except second-

 

ary interface, the interface for DTE timing, or the mul-

 

tiport DBU. If other interfaces have any restriction on

 

their location, this will be specified in the individual

 

option card manual (provided with the option cards).

Slot 6

Slot 6 services any option module type including sec-

 

ondary network interface ports (DSX-1 (PBX) and Full

 

D&I), but not the DTE timing source. If a secondary

 

network interface port is to be used, it must be

 

installed in slot 6.

You can use NxDBU modules in any slot.
