26. EXTENDERS PAGE 56 of 56 Frequently Asked Questions Q Why does it take so long for the propagation of off hook to on hook transitions A The line balance ac coupling capacitors take some time to charge Also the delay helps to prevent audio from looking like an on hook condition Q Why does it take so long for the propagation of the page line ground fault transitions A If the delay was not there then page line audio might appear to be a ground fault Q Why is shielded cable specified for the LVDS cable A To improve the link s noise immunity Most likely the clock signal that controls one of the LE300s passes over the LVDS cable Q Is the LE300 compatible with the public switched telephone network A No Q Does the LE300 have on board primary protection for the T1 E1 cable A No Q Why is the LE300 not compatible with the public switched telephone network A 1 It is not approved for such use 2 At a minimum it does not support the facility data link transmission required for such use Q CanI connect a Model LE300 to an LE200 A Yes these units are electrically compatible only mechanical changes were made between the LE200 and LE300 Q Can I connect a Model LE300 MM to a LE200 FSR or a Model LE300 SM to a LE200 FLR A No the units contain different fiber optic transceivers and are not compatible The fiber optic transceiver unit in the LE200 series line extender must be changed to match t
