SPECIFICATIONS
As of the date this Instruction Data Sheet was published, the following specifications apply to the RFL
VF-5XP module. Because all of RFL products undergo constant refinement and improvement, these
specifications are subject to change without notice.
Configuration:
Two independent voice channels per module.
Time Slots Required:
Channel One: Requires one user-selectable 64-Kbps time slot.
Channel Two: Requires two 64-Kbps time slots. (Must be after channel 1’s time slot)
Remote Interface:
All settings can be changed in remote mode using NMS, except E&M signaling type. Access to
status registers, including board and firmware revision levels, is also provided through NMS.
