informs the equipment to hang up.
8.6.1.3 Option 2. Wink-Start to Ground-Start Conversion
POTS Interface
This option provides a POTS (Plain Old Telephone Service) ground-start interface between the
Access Bank II - SNMP and the PBX or other phone equipment. This avoids both-way call collisions
(“glare”) on PBX trunks and gives the PBX a disconnect signal when the far-end party hangs up.
E&M wink-start signaling and ringback tones are sent to the T1 line on an individual channel basis.
This option is for use with AT&T Megacom

or equivalent E&M services from
other service providers.
8.6.1.4 Option 3. E&M Immediate-Start-to-Loop-Start Conversion
Private Line Automatic Ringdown (D3 PLAR)
Known as D3 Private Line Automatic Ringdown (D3 PLAR), this option provides a “hot-line” ring
down function from the near-end telephone to the far-end telephone connected over the same channel
of the T1 line. The first telephone to go off-hook seizes the channel with a signaling bit sequence of
A/B = 11 and hears a cadenced ringback tone (2 seconds on, 4 seconds off) from the far-end channel
bank. The far-end disconnects the ringback tone and sends A/B = 11 to the originating end when its
telephone goes off-hook. D4 PLAR is not supported.
To use this option, order E&M immediate-start service from your service provider.
8.6.1.5 Option 4. E&M Immediate-Start-to-Ground-Start Conversion
This is the same as the E&M immediate-start-to-ground-start conversion option for services such as
AT&T Megacom and NYNEX Flexpath.
To use this option, order E&M immediate-start service from your service provider.
