Lil' Buttie RANGER

4.9.6 On-Hook Caller ID

While it's in BELL or MONITOR mode, the Ranger
detects and displays on-hook Caller ID information.
The Ranger doesn't block the first ring signal. If the
Ranger or another phone on the line is taken off hook
before the beginning of the second ring, the Caller ID
information might not be properly received. Because
the Ranger has a small screen, it only displays number
and name information (when these are available).
However, the Ranger is capable of receiving messages
of any type and length (as long as they're formatted per
Bellcore GR-30-CORE) and verifying their checksums.
Besides name, number, "out of area," and "numbers
blocked," the messages listed below are displayed by the
test set as required:
• "Single Msg Type" – The Ranger correctly
received a Caller ID in single-message format.
but the message was an unsupported type.
• "Multi Msg Type" – The Ranger correctly
received a Caller ID in multiple-message format,
but one or more sections of the message were
unsupported types.
• "Chksum=xx, Rx=yy" – The Ranger has detected
a checksum error. The checksum xx was at the
38
end of the message, but the Ranger calculated
the checksum yy from the received data.
• "Lost Carrier" – The Ranger detected the
Caller ID carrier, but lost it before the end
of the transmission.

4.9.7 Call Waiting Caller ID (CWCID)

The Ranger in TALK mode handles off-hook Call Waiting
Caller ID (CWCID) essentially the same way it does on-
hook Caller ID, displaying the same information and
errors. But instead of the first ring alerting the Caller ID
circuitry, a special CPE Alerting Signal (CAS) tone is sent
immediately after the usual Call Waiting alert tone. When
CWCID is enabled, the Ranger detects this tone, mutes
its audio circuits, sends an acknowledgment tone, and
receives the data before re-enabling the audio circuits.
Because the CAS-detection circuitry requires considerable
battery power (about 3 times the normal TALK-mode
battery power), the default setting for CWCID is "OFF."
To enable CWCID, you'll need to access the setup mode
(see Section 4.6).

4.9.8 DigitView DTMF Decode and Display
In MONITOR mode, the Ranger decodes and displays
any DTMF tones that are on the monitored phone line.
