Assigning Time Slots to a User Card System Configuration and Operation
Figure 3-15. Time Slot Assignment Example
Each port of the E&M card can only be assigned a single WAN time slot, or 64 kbps of
bandwidth on a T1 or E1 link. The same is true for the ports on all other types of voice cards.
However, each port of an HSU data card may need multiple WAN time slots, depending on
the data transmission rate of the associated CPE. In Figure 3-15, eight time slots are assigned
to port 1 of the HSU card, so its aggregate rate is either 448 kbps (at 56 kb per channel) or 512
kbps (at 64 kb per channel).
All other user cards are assigned WAN time slots in a similar manner. Refer to the individual
card chapters for specific instructions.
3.10.1 Assigning a Time Slot to a User Card Port
You can define a time slot map from any user card (data or voice) for connections involving
that card, or from a WAN card for cross-connections involving only WAN cards. For example,
Figure 3-16 shows the E&M Card Main Screen for the time slot assignments. Assign time
slots to a voice card as follows:
1. From the System Main Screen, select the desired voice card and press <Enter>. That
card’s Main Screen appears.
2. Select the WAN port from which you want to assign time slots to the E&M card. In
Figure 3-16, this is
W1-1
(for WAN 1, port 1).
3. Select a time slot (TS) for the first card port. A number appears at the bottom of the
screen for the corresponding time slot on the WAN port.
