The timing parameter indicates the timing signal to be used for transmission. A value of INT (for
internal) indicates that the Universal Trunk should generate the transmit clock internally from its
precision oscillator. A value of NET (for network) indicates that the Universal Trunk should
recover the transmit clock from the receive data stream and use it for transmission.
It should be noted that there may only be one master clock in the DSU interface between
components, and there must be one master clock in that interface.
The tsrate parameter indicates the type of timeslot to be used. This is used for DDS and Frame
Relay protocols, which may be connected to a remote channel bank at 56K instead of 64K.
Please note that the ATM protocol must have 64K timeslots.
The addslot parameter allows the user to map a timeslot in the usage map. This allows fractional
T1/E1 from one timeslot to all of them (24 in T1 and 30 in E1).
Note: With E1 framing, the first timeslot, and the 16 th (17 th counting from one) is not
usable per the ITU standard (G.704, G.706, G.703).
The addslot parameter allows the addition of a single time slot, or all of them defined for the DSU
type. The numeric range is one through 24 for a T1 DSU, and one through 32 for an E1 DSU
where one, and seventeen are not configurable.
The delslot parameter allows the user to remove a timeslot from the usage map. All of the
timeslots may be removed with the all option.

The trunk command configures the protocol to be used between components, and associates the
physical interface to the protocol.
