DIGITAL TELE AID CONTROL MODULE 

SERVICE INFORMATION

Notes on D2B optical fibers

• Optical fibers damage easily-handle optical fibers with care to prevent cuts, nicks, abrasions, and crushing.
• Optical fiber "ring configurations" must form a closed loop to function (i.e. couple the input of a component with the output of the preceding component).
• Identify D2B optical fibers by their orange, semi-rigid insulation.
• Electromagnetic interference (EMI) from bundled vehicle electrical harnesses does not affect optical fibers.
• The digital Tele Aid control module for vehicles equipped with ECALL2 has a D2B port. Do not connect the D2B port of the digital Tele Aid control module if the existing analog Tele Aid control module has no D2B port. Include the digital Tele Aid control module in the D2B ring configuration only if the existing analog Tele Aid control module has a D2B port.
