RE: Please help to clarify some things!
Let me try this one more time, then I'll give up. Is it (a) or (b).
Sounds very much "What is not used... " like (b) to me.

Again, you are confusing the issues. Out of band network management can use
as the transport protocol. TL1 over TCP/IP is commonly used. What is not
is element and network management based on SNMP in band with the customer
for transmission network elements. IS-IS is also used as the transport
for transmission network element and network management. The element
protocol for IS-IS is CMISE/Q3.
