Customizing HotWire 7924 Nest Card Termination Units
Operating unframed while T1 service is framed will result
in the loss of reporting certain performance statistics, for
example, CRC.
Configure your HotWire equipment to match the T1
network. If your T1 service is framed, configure your
HotWire 7900 nest cards as framed. If your T1 service is
unframed, configure your HotWire 7900 nest cards as
unframed.
