Mine showed up fine so could be your local exchange? Or your equipment. Or power cut.
Not likely to be the exchange as my other line was fine.
Not likely to be my equipment as both lines share the same router.
Power Cut? Where? Neither here nor the exchange. Could it be the FTTC cabinet? (Zen is FTTC. AAISP is ADSL)
