1. Once opened select 1x64 for a single
channel or nx64 for multiple channel
selection from the dropdown menu.
2. Select the required timeslots using the
directional and enter keys as required.
3. Press the Esc key to deactivate the
list section and use the directional
keys to select OK or to move to

Note: The ANT-5 will only be able to transmit and receive nx64 when E1 framing is
part of the hierarchy. Channel 0 is used for FAS/NFAS and will always be greyed out;
channel 16 (used for signalling purposes) will be greyed out if either PCM30 or
PCM30C are selected as part of the framing structure.
4.22 STM-16 Functionality
An enhanced ANT-5 (BN4565/03) manufactured after December 2002, extends the
maximum bit rate up to 2.5Gbit/s (STM-16/OC-48).
4.22.1 STM-16 G957 Optical transmitter and receiver
Configure the transmitter and receiver as
required. Refer to section 4.4 and its sub-
sections, which describes in detail the settings
for the signal structure.
In this example STM-16 Optical has been
selected as the rate.
The STM-16 transmit signal is constructed
using one STM-1 internally generated signal
(AU-4/AU-3), the other 15 tributaries are loaded with HP-UNEQ. Refer to section 9.4.4
for the G.957 specification.
