This parameter defines a situation where due to abnormal trans-hybrid losses and even when the trunk is in the "on-hook" state, some energy may appear at the speech detector at high enough levels to activate the speech detector. The transmit on-hook scheme allows the state of the channel to be identified through a specific pattern of the 2 signalling bits of the 4-bit signalling scheme for 1544 and 2048 kbit/s trunks. In this case, "transmit" refers to the direction into the CME from the channellize side. This attribute is characteristic of CME. It falls in the TMN Configuration Category. It is a Read/Write attribute that has Enumerated Option values of A/B: 0/0, 0/1, 1/0, 1/1, 0/don't care, 1/don't care, don't care/0, don't care/1, always on-hook, always off-hook The default value is: always off-hook Comment: The on-hook signalling scheme should be set to "always off-hook" when common channel signalling is used in an application to prevent degraded performance, for example clipping of speech or transmission errors.
