Hi,
I've tried to post this before, but either the message didn't make ist
out or nobody answered B-{(
ISO/IEC DIS 10022 describes the "Physical service definition", i.e. the
interface between Layer 1 and Layer 2.
It describes the interface in terms of primitives:
- Activation
- Data Transfer
- Deactivation
One of the activation primitives (Ph-ACTIVATE request) is used to
establish a connection between two PhC endpoints.
When one uses a modem with dialing protocol V.25bis or an X.25
connection, the connection establishment phase uses a different
configuration on the "control lines" while dialing.
Questions:
1. Is this dialing part of ISO layer 1 (physical layer)?
In my opinion, it is.
2. How do I specify the address/numbers to use?
DIS 10022 only says that parameters to the activation primitives
concern the classes of service, but no mentioning of any dialing
parameters.
