Enumeration
Timestamp generation MAY be used in one of the following
modes:
1. Absolute mode: The PSN-bound IWF sets timestamps
using the clock recovered from the incoming TDM attachment
circuit. As a consequence, the timestamps are closely
correlated with the sequence numbers. All TDM
implementations that support usage of the RTP header MUST
support this mode.
2. Differential mode: Both IWFs have access to a common high-
quality timing source, and this source is used for timestamp
generation. Support of this mode is OPTIONAL.
Object MAY be changed only when the related PW is
defined as not active.
