Networking considerations for recovering CTC/BSC communication lines

If you use channel-to-channel (CTC) adapters or binary synchronous communication (BSC) lines to connect your JES3 complex to other nodes in your network, and your networking line fails, perform the following steps to recover the failing line:

1. Ensure the input/output supervisor (IOS) path is still active. If the path is inactive, IOS issues message IOS002A. Enter an MVS™ VARY command to reclaim an IOS path.
2. Activate the networking line by entering the *CALL,NJE command.
