Values:

The transfer delay is encoded in a single hexadecimal octet. By interpreting this hexadecimal octet as an unsigned integer n, the transfer delay  applicable to the PDP context can be calculatd as follows:

                0 < n < 15             n * 10ms                                 (0 < d < 150)

                16£ n < 32            200 +(n-16)*50 ms             (200£  d < 950)

                32£ n < 64            1000 +(n-32)*100ms         (1000 £  d < 4100)

The value n = 0 indicates the subscribed  Transfer Delay (only applicable to UMTS Quality Of Service Requested), all other values are reserved.
