Verizon/Fairpoint Circuit descriptions
This would apply to Verizon (now Fairpoint) territories here in Maine. Not sure if this is company wide.
ARDU – dry loop with no Verizon services on it
TXNU – lineshare DSL + Voice, possibly mixed ILEC circuit with ILEC Voice and CLEC DSL service on it
ARDA – Verizon only circuit, voice + DSL
Where would I find this circuit identification? Possibly written in the NID or on a circuit identification tag in the NID on the wires.
Telco ILEC/CLEC ANAC numbers I’ve collected
Definition of an ANAC here.
Verizon ANI – 200-1111 or (untested) 200-1234 or (dead?) 10111
GWI – 311
Fairpoint – 958
MCI – 1-800-444-4444 (not actually an ANAC, but the IVR reads off the phone number)
