| Overview: |
These TIA standards describe the
requirements for Caller ID capable Customer
Premises Equipment (CPE) in both the on-hook
(type I) and off-hook (type 2) modes of
operation. Similar to the Telecordia SR-3004
document, the TIA documents cover both the
physical and data layer aspects of Caller ID
transmissions. Additionally, the TIA/EIA-777
standard provides the requirements for Multiple
Extension Interworking (MEI) functionality. MEI
allows for multiple type 2 telephones to
correctly receive Caller ID information when
either in the on-hook or off-hook state. As such,
the call logs for all MEI compliant telephones
will be consistent with each other. Non-MEI
compliant telephones can contain different call
logs and prevent type 2 Caller ID data reception
when off-hook. In addition, MEI provides Call
Waiting with Disposition (CWD) functionality with
multiple telephones in the off-hook state. For
CAS (CPE Alerting Signal) detector testing, the
TIA/EIA-777 document references the testing plans
contained in the Telecordia SR-3004 and
SR-TSV-002476 standards. |
