Ces Service Details Screen - Paradyne Hotwire 8300 User Manual

CES Service Details Screen

Selecting CES under the Type column of the table in the Services screen will
display the CES Service Details screen show in
Figure 3-34. CES Service Details Screen
From this screen, you can access and change the parameters listed below. The
new parameters are saved when you ESC from the screen and perform a Save
and Restart.
VPI Determines VPI used for this CES Internet Working Function (IWF). The default is
0.
VCI Determines VCI used for this CES IWF. The default is 33.
Service Type Determines if T1/E1 service is structured (Nx64 kbps with or without signaling) or
unstructured (2.048 Mbps or 1.544 Mbps raw data stream). You must configure
the Service Type to correspond with the desired CBR port framing and channel
rate in accordance with the table on page 3-39.
Timing Determines the CES services clocking mode, which maps to the transmit clock
source of the CBR interface and Serial interface (if configured for a CES service).
When Adaptive timing is selected, the receive AAL1 payload buffer is monitored
for predetermined threshold levels to control the frequency of the interface clocks.
When the buffer depth exceeds the predetermined upper threshold, the interface
clock frequency is increased to cause the buffer to drain more quickly. If the buffer
depth falls below the predetermined lower buffer threshold, the interface clock
frequency is decreased to cause the buffer to drain less quickly. Both lower and
upper threshold levels are used in conjunction with Cell Delay Variation to provide
hysteresis around threshold levels.
