Digium analog tdm410p

plz Tell me,
What is Problem… Show RED in Fxo Port.

[trixbox1.localdomain asterisk]# lsdahdi

Span 1: WCTDM/0 “Wildcard TDM410P Board 1” (MASTER)

1 FXO FXSKS (In use) (SWEC: MG2) RED
2 FXO FXSKS (In use) (SWEC: MG2) RED
3 FXS FXOKS (SWEC: MG2)
4 FXS FXOKS (SWEC: MG2)

At a guess, no battery voltage (from the upstream exchange) on the pairs connected to those ports.

Is there any reason why this card is not eligible for support from Digium, as this is not a place where Digium provide support?
