DTMF and Dial Tone Circuit Setup 
If the system has 2500 type (DTMF) single line
 
extensions, allocate at least one circuit for
 
analog extension DTMF reception (0 or 1). 
Use the following as a guide when allocating
 
DTMF receivers: 
 In light traffic sites, allocate one DTMF
 
receiver for every 10 devices that use them. 
 In heavy traffic sites, allocate one DTMF
 
receiver for every five devices that use
 
them. 
 The GCD-CP10 has 32 resources for DTMF
 
receiving and Dial Tone detection. When a 
GPZ-BS10 is installed there are 64 resources
 
available. 
 When Program 10-09-01 is set to 0 (Common)
 
and  Program 14-02-10 (Caller ID) is set to 1 (Yes),
 
all DTMF/Dial Tone Detection resources are always
 
allocated to analog trunks, not analog extensions.
 
However, if Program 14-02-10 (Caller ID) is set to 0
 
(No), all DTMF/Dial Tone Detection resources can
 
be used for both analog trunks and analog
 
extensions. 
Single Line Telephone Basic Data Setup –
 
SLT Signaling Type 
Enter 0 if single line telephone is a 500 type
 
(dial pulse). Enter 1 if single line telephone is a
 
2500 type (DTMF). 
 Set In-Skin Voice Mail and InMail to 0. 
Single Line Telephone Basic Data Setup –
 
Terminal Type 
Enter 1 for this option to allow a single line port
 
to receive DTMF tones after the initial call
 
setup. Enter 0 to have the port ignore DTMF
 
tones after the initial call setup. For Voice Mail,
 
always enter 1 (e.g., receive DTMF tones).
