Z-Edge 64 Configuration Guide
First set ADPCM voice compression on the Z-Edge 64:
zSH> new aal2-cid-profile 1-1-1-0-hdsl2/atm/0/37/160
Please provide the following: [q]uit.
admin-status: -------> {down} up
sscs-type: ----------> {i3662}
audio-service: ------> {enabled}
frame-mode-data: ----> {enabled}
cas: ----------------> {disabled}
pcm-encoding: -------> {mulaw}
max-length-frame: ---> {65535}
max-sdu-length: -----> {1536}
ras-timer: ----------> {0}
preferred-ap-index: -> {1} 2

Save new record? [s]ave, [c]hange or [q]uit: s
New record saved
Then set ADPCM voice compression on the other end of the voice
connection, ensuring matching VPI/VPIs and CIDs between the nodes.
Changing from G.711 to G.726 encoding
To change from G.711 to G.726 encoding on pre-existing aal2-cid-profiles:
1
Update the pre-existing aal2-cid-profile, changing the admin-status to
down.
2
Change the preferred-ap-index to 2.
3
Save the record.
4
Update the aal2-cid-profile again, changing the admin-status to up.
5
Save the record.
Note:
You must change the admin-status to down and then up again
for voice encoding changes to take effect on pre-existing
aal2-cid-profiles.
POTS voice options
On the Z-Edge H2A, there are several voice digital signal processing (DSP)
options which you can modify in the analog-if-cfg-profile and the
analog-fxs-cfg-profile records.
Configuring POTS gain settings
Modify the following parameters in the analog-if-cfg-profile if you need to
change the gain settings for each POTS voice line:
