This object specifies the jitter buffer size in
milliseconds (ms).

Default value depends on the CEM SAP endpoint type
(sapCemEndpointType), and if applicable, the number of
timeslots (sapCemBitrate):
---------------------------------------------------------
| Endpoint Type      | Timeslots | Default jitter buf.  |
---------------------+-----------+-----------------------
| 'unstructuredE1'   | n/a       |    5 ms              |
---------------------+-----------+-----------------------
| 'unstructuredT1'   | n/a       |    5 ms              |
---------------------+-----------+-----------------------
| 'unstructuredE3'   | n/a       |    5 ms              |
---------------------+-----------+-----------------------
| 'unstructuredT3'   | n/a       |    5 ms              |
---------------------+-----------+-----------------------
| 'nxDS0' (E1/T1)    | N = 1     |   32 ms              |
|                    +-----------+-----------------------
|                    | N = 2..4  |   16 ms              |
|                    +-----------+-----------------------
|                    | N = 5..15 |    8 ms              |
|                    +-----------+-----------------------
|                    | N >= 16   |    5 ms              |
---------------------+-----------+-----------------------
| 'nxDS0WithCas' (E1)| N         |    8 ms              |
---------------------+-----------+-----------------------
| 'nxDS0WithCas' (T1)| N         |   12 ms              |

Configuring sapCemPayloadSize and sapCemJitterBuffer to
values that result in less than 2 packet buffers or
greater than 32 packet buffers is not allowed.

The valid range is 1 to 250 ms.  Setting this object
to 0 sets it back to the default value.
