====== BT NTE51 & NTE52 ======

Another x21 / G703 NTE, these have incoming circuits presented over sdsl on two pairs of copper. \\

These are both used to present primary rate ISDN circuits to a Cisco WIC card.

Both these units are line powered.


===== NTE51 =====

According to the LEDs, this can present 1MB/s or a 2MB/s connection.

The first pic shows normal operation, the second was taken during an outage on the BT (SDSL) side.
Normal operation is for just the one green LED to be on, in the second pic, the SHDSL is in a fault condition.
