tx steering (cross busy)

English to Hebrew Tech/Engineering Telecom(munications) broadcasting, radios (walkie-talkie)

I'm looking for the Hebrew terms for these two phrases.

Tx Steering is when a transmission is steered from one origin (antenna, etc.) to another (for better reception, for example), and cross-busy means when input comes into a busy port, it is sent to another port.

Reference (from a different product):
Although LTR overlay will work with any conventional controller, the
TP-163 by Connect Systems Inc. has a X BUSY (meaning cross busy) input
which busies out the TP-163 (makes unavailable) if LTR is currently
using the channel. (The LTR conversation will trunk to another channel
at the first break if a conventional user is attempting access).

Tnx,
Motty.
