in MGCP Q.931 Backhaul, "show isdn status" layer 2 status is TEI-assigned.

in documentation, it said layer 2 status should be   MULTIPLE_FRAME_ESTABLISHED

but in my real world router (which isdn/pri is working fine), I saw the layer 2 status is TEI-assigned.

so which status should be good exactly?

Hello,

Is it an ISDN BRI or PRI? In most BRI cases Telco use power saving so it will only become "MULTIPLE_FRAME_ESTABLISHED" when a call is placed but when idle it will stay "TEI_ASSIGNED".
