3.10 Time Slot Assignment
This section provides instructions for assigning DS0 time slots to the voice and data ports of
the IMACS-200. It also provides time slot cross-connection setup instructions.
The IMACS-200 maximizes the use of incoming and outgoing T1 lines. You can do this by
assigning specific channels, or DS0 time slots, to voice and data ports in the system. You also
can cross-connect time slots between T1WAN ports of the system.
The WAN port allows you to connect one DS0 time slot to another. Throughout this chapter,
these connections are called "pass-through" circuits because they link a time slot from one T1
line to another through the system. You can therefore have up to four separate T1 links on two
WAN ports, in any cross-connect combination.
The following sections of this chapter describe several ways for you to administer your
networks and correctly allocate transmission bandwidth to meet your needs. The next section
deals with assigning time slots to the user voice and data port.
The third section deals with cross-connecting WAN time slots to other WAN time slots.
The fifth section describes signaling status, signaling, and companding conversion. The last
section shows you how to view the time slot map after making your assignments and
cross-connections.
This chapter defines "assigning time slots" as the process of connecting user port ports to
WAN ports and time slots, and it defines "cross-connecting time slots” as the process of
connecting WAN time slots to other WAN time slots in the system.
