Administering the Analog Adjunct on the
Modular 6424D+M Telephone
As noted above, all 6424D+ and 6424D+M telephones can be administered as
themselves ONLY IF they are connected to a DEFINITY ECS Release 6.1 (or
later). In Native Mode the Modular 6424D+M telephone is administered through a
digital line circuit card with a line number (with the usual three call appearances)
assigned to the I-1 Channel. If the Modular 6424D+M is connected to a DEFINITY
ECS Release 8.1 or later, a second line number can be administered through the
same digital line card on the I-2 Channel, but this line number can only be used for
analog adjuncts connected to the Tip/Ring module. This analog adjunct is
assigned a private number, but can be used only for placing or terminating a call.
It cannot be used for any other analog functions such as transferring a call or
setting up a conference call. If a second line on the telephone is administered on
the I-2-Channel (for analog equipment), type “analog” in the Data Option field on
the administration screen.
Power Failure Operation
The 6400 Series telephones cannot be used as an emergency station during
power failure transfer conditions.
FCC Registration
The 6400 Series telephones are FCC-registered along with the switch (as a
system), but do not have a separate FCC registration label.
UL and CSA Approval
The 6400 Series telephones have been tested and have met the Underwriters
Laboratories (UL) Standards UL 1459 and have also met the Canadian Standards
Association (CSA) Standards CSA-C22.2 No.225-M90.
Hearing Aid Compatible
All 6400 Series telephones are compatible with the inductively coupled hearing
aids approved by the FCC.
