2. Plan the Interface
The system administrator programs the telephone system for use with the Wireless 
Telephone System using the normal administration terminal or procedures. 
Programming can be done after the handsets are registered. 
Recommended programming includes assigning extension numbers to the handsets 
and programming features on the telephone system so they are easily accessible from 
the handsets. 
For analog interfaces, macro codes are in the document relating to configuring the 
system. See Link 3000 MCU: Operator’s Console, Link 150 M3 MCU: Installation 
and Operation, or NetLink Telephony Gateway: Installation, Configuration, and 
Administration. 
The following information will help the system administrator set up the SpectraLink 
handsets to operate in a way that feels familiar and comfortable to users. 
2.1 Plan Programming
Digital Interface programming for the Wireless Telephone System will be faster if it 
is planned in advance by verifying the parameters and features on the current 
telephone system and wired phones. The system administrator must assign extension 
numbers to the handsets and plan the functions (trunk access, toll restrictions, 
system features, ringing options etc.) to be programmed for the handsets. 
One of these scenarios concerning how the handsets are programmed should apply 
to this site: 
• All handsets are programmed alike – All handsets will be programmed exactly 
the same. Depending on the capabilities of the switch, the system administrator 
can often program one handset and use it as a model for all other handsets. 
• Groups of handsets are programmed alike – Handsets are grouped into classes
that are programmed alike. Depending on the capabilities of the switch, the 
system administrator can program “model” handsets then use the model as a 
template to program the other handsets. 
• All handsets are different – All handsets are programmed differently, so each
handset will be programmed individually.
Before the system is installed, verify the operating parameters and features on the 
Rolm system and sets, and set up template tables to reflect the required parameters 
and features for the handsets. Programming will be faster if you determine this 
information in advance. 
Line Assignment 
The handset supports a total of nine line resources. Which lines should ring at this 
handset? 
Extensions 
Which extensions will be assigned to the handsets?
