In the iPECS-MG system, WTIB4 and WTIB8 are both Base Station interface boards. The iPECS-MG System can have up to two (with MPB100) or three (with MPB300) WTIB4 (up to 4 ports) or WTIB8 (up to 8 ports).
CAUTION
1. Prior to installing the WTIB4 System power should be turned OFF, to avoid any damage.
2. If the WTIB4 is plugged back into the System after being removed, the WTIB4 should be plugged into the original slot to avoid the loss of programmed data.
The WTIB4 can be installed on universal slot 1-6 of any KSU except slot 1 of 1st KSU and should be installed on the same KSU when installing more than one WTIB4/8.
CAUTION
The Base Station is connected to the WTIB4 by an unshielded twisted pair cable (at least CAT3).
NOTE:
1. The unshielded twisted pair cable (at least CAT3) should be used to connect WTIB4 with a Base Station.
2. Shielded cable can be used if it can withstand interference from noise sources such as an AC power cable with high voltage. A shorter cable length and/or clear line-of-view between the WTIB4 and Base Station will decrease the possibility of data degradation.
3. Even though there are connection points such as MDF or the connection tab between WTIB4 and Base Station, the connection points should be connected with twisted-pair cable (at least CAT3). For example, WTIB4 to MDF, MDF to MDF, MDF to connection tab, and connection tab to Base Station should be joined using twisted-pair cable.

NOTE:
1. Using unshielded twisted-pair cable (more than CAT3), wire the Base Station RJ-11 to the termination point/MDF for connection to a WTIB4.
2. Tag or number wiring for maintenance.
