CAS/Dual Tone Alerting
The CPE Alerting Sequence (CAS) tone is an Alerting Signal sent down the telephone line
to inform CPE that a CIDCW/SCWID message is waiting. This CAS tone is sent after the
SAS tone and will wait for a DTMF ACKnowledgement before transmitting CID data. The
CAS tone is programmable as Disabled, Single Tone, Tone 1 + Tone 2 or Tone 1 x Tone
2. The frequency is programmable from 10 to 3000 Hz in 1 Hz increments and the signal
level is programmable from -6 to -60 dBm in 1 dB increments.
FSK Tone(s)
The FSK tones are comprised of a Mark (1) and a Space (0) frequency. The Mark
frequency may be set from 1100 Hz to 1400 Hz and the Space frequency from 2000 Hz
to 2300 Hz in 1 Hz increments. The signal level for each frequency is programmable from
-10 dBm to -60 dBm in 1 dB increments.

Note: This screen will be hidden if ETSI DTMF is NOT selected for any of the four Lines. See
Figure 35.
The TLE-ICID module allows the user to configure many parameters associated with
DTMF based Caller ID. These parameters include the DTMF Mode, Information Code,
Normal/Private/Out of Area transmissions, and DTMF Generation details.
The DTMF Mode supports the following DTMF transmissions, all associated with Ringing:
Calling Number only
Calling Number and Diverting Number
Diverting number only
Calling Number, Diverting Number, Call Forward, and Information Code
Private (restricted) code delivery when a ∗67 (default) prefix is dialed
