Capacity defaults to 25M for ATM native connections.

Specifies the effective capacity of the link that comprises the transmission group (TG). Specify the value in Kb per second (for example, 100K), Mb per second (for example, 100M), or Gb per second (for example, 10G). This number approximates the bits per second that the link can transmit (the transmission rate of the link, times the maximum load factor expressed as a percentage).

Note:

Because the value for capacity is represented as a single byte, the precision of the specified number of bits might be lost. For example, numbers that are close (such as 100K and 101K) can be interpreted by VTAM®, and displayed, as the same value. See Table 1 for a list of CAPACITY values you can specify and their corresponding values when displayed.
The capacity specified for ATM native connections defined as reserved bandwidth should be related to the forward sustainable cell rate (DLCADDR subfield 7). To calculate the data throughput required for a reserved bandwidth connection, multiply the sustainable cell rate by the payload per cell (48 bytes). If the defined CAPACITY is greater than ten times the ATM reserved bandwidth connection capacity, excess storage might be used and the weighting of this TG with others might cause undesirable results.
