Configures maximum transmission unit for the GPRS interface.
14.1.15.2 Usage
Attribute Type: Read/Write
The maximum transmission unit is a part of the configuration that determines
largest data packet that can be sent over the GPRS interface before
defragmentation is required. In certain cases this can be used to optimize
communications interface speeds.
Providing value zero normally works, but some networks might require some
tweaking.
Recommended values for the various communication types are
GPRS over GSM/GMSK: 576
GPRS over GSM/EDGE: 1476
GPRS over UMTS/WCDMA: 1500
Format on getting parameter:
<MTU>
where <MTU> is the maximum transmission unit, <MTU> >= 0.
