Description: The Iteration Register needs to be programmed in SRM when DSO drop loop option is selected in bertDeviceToLoop. The value to be programmed there is minus one of this object value, since the register is 0 based. DSP-OP devices can be cross connected in the centeral office. By this, the user has capablitiy to put any of the devices in the chain in loopback mode. This is done by repeating the latching activation code in a specific manner. The binary number in the iterataion register determines how many times the first portion of a latching loop activation code needs to be repeated as per user request and according to the Bellcore spec. A value of 0 results in no iteration and will cause the very first device in chain to go into loop back. A value of 1 will result into one iteration and will cause the second device to go into loopback and so on. The range of this count is 1 to 32, and it would translate to a range of 0 to 31 for the iteration register.
