Incoming calls
The far-end initiates calls as follows:
• The ground is placed on the E lead in E and M signaling.
• Dial pulses are subsequently applied from the far-end as ground open on the E lead.
• If the far-end is equipped for sending, the system can operate in any mode (immediate
start, delay dial, or wink start), as assigned on a start arrangement basis. See
Operation Mode
- In immediate start mode, there is no start signal from the called office. The seizure
signal (off hook supervisory state) from the far-end should be at least 150 ms. At the
