2.11 95T GPI BRM / DLM Direct line modem interface.
The 95T GPI BRM and 95T GPI DLM interfaces are used when the distances between two bus systems are
more than 1.2 km and where it is not possible to use the 95T GPI DLC bus amplifier.
The maximum distance between the BRM and DLM interfaces are specified by the modem supplier. The 95T
GPI BRM and 95T GPI DLM interfaces must always be used together. Seen from the system (AIMS
software) the readers connected after the modem line are shown as if a Bridge was installed. Maximum 31
readers can be installed at the end of the modem line.
