DATA EQUIPMENT/12.0 The data system can handle a maximum of 120
ENGINEERINGdata ports. This section provides a general configuration
overview, detailed configuration rules and limitations, and
procedures for engineering the data system.
The following parameters describe the customer requirements to
configure or add on a data switch:
APM= Tl + T2 - T3
where 
Tl = number of asynchronous data terminal ports
requested (maximum speed = 19.2 Kbps) (VPLO or
VP20)T2 = number of asynchronous host...

TL-130500-1001
Compute the hardware quantities as follows:
1. Compute the total of asynchronous terminals (with and without
modems), plus asynchronous host ports (with and without
modems), plus asynchronous modems in modem pools. This
total is the number of APMs or DPF/APM required.
2. Determine any other 
DFP/APM required.
3. The X.25 terminals and host ports must be split into two
groups, depending upon line speed. Those which operate at
19.2 kbps or less fall into the first group, which uses a SPM...

To connect the LPB into one bus in the top file of the PEC, add
jumper wires between slots X24 and X25, pins 36-40 and 86-90.To connect the LPB into one bus in the bottom file of the PEC,
add jumper wires between slots Y26 and Y28, pins 36-40 and
86-90.Example: X24 pin 36 to X25 pin 36
