Wink-Start to Ground-Start Conversion (AT&T Megacom, Flexpath, etc.)

Access Bank FXS interfaces can convert from E&M wink-start to a standard Ground-Start interface to a

PBX phone system. 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 per-channel ringback

tones are provided to the T1 line.

E&M immediate start to loop start (also known as Private Line Automatic Ringdown - PLARD

Private Line Automatic Ringdown (PLARD) provides a "hot-line" ring-down functions from the near-end

telephone to the far-end telephone connected on the same channel of a T1 line. The first telephone to go

off-hook seizes the channel with an 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

channel when the connected telephone goes off-hook. This is the signaling sequence for D3 PLARD

operation. Note that this is the same signaling as the E&M immediate-start to loop start conversion

option for services such as AT&T Megacom and Nynex Flexpath.
