Surrogate Mode Programming 8
Surrogate mode allows qualified service personnel to perform system 
programming at an offsite service location. The actual system hardware does 
not have to be installed — the programmer needs a power supply, carrier, 
processor, and a direct connection from the PC to the processor module. By 
following a customer’s set of completed planning forms, the system can be 
programmed as if the appropriate modules, trunks, telephones, and other 
communications equipment have been installed. When system programming is 
completed, a system backup is performed to save the information on disk. This 
backup disk is then taken to the new installation site and used with the Restore 
option to provide complete system programming for a new system.
Accessing Adjunct ports using 
ss/pp for TDL Modules
8
The slot/port number displays sspp to distinguish the 2-digit slot number from 
the 2-digit port number. Slot is the slot number in the carrier and port is the port 
number on the module. 
Just as with MLX modules, the slot/port numbering for adjunct ports 
on 412 LS-ID-TDL modules begins at 21. The slot/port numbering for 
adjunct ports on a 024-TDL module begins at 25. For example, on a 
412 LS-ID-TDL module in slot 1 of the carrier, to access adjunct port 
710, you would enter 0121 as the slot/port number (01 indicates slot 
1 on the carrier) while on a 024-TDL module in slot 1 of the carrier, to 
access adjunct port 710, you would enter 0125.
