2. | Introduction of this service in the shore to ship direction has a limitation that such short duration metering pulses cannot be transmitted over junction cables and mechanical meters in electro-mechanical exchanges cannot respond to these pulses as such this facility cannot be made available in electro-mechanical exchanges. However, in all other local electronic switches the pulses may be generated locally and services via INMARSAT opened. In C-DoT 256 Port RAX and ILT switches, these services cannot be implemented on account of technical constraints. |
