| Description | Cadence rings are defined by the telco governing
body for each country. The MTA must be able to support
various ranges of cadence patterns and cadence periods.
The MTA will be able to support country-specific
provisioning of the cadence and idle period. Each
cadence pattern will be assigned a unique value ranging
from 0-127 (inclusive) corresponding to the value of x,
where x is the value sent in the cadence ringing (cr)
signal cr(x), requested per the appropriate NCS
message, and defined in the E package. The MTA will derive
the cadence periods from the ring cadence table entry, as
provisioned by the customer. The MTA is allowed to provide
appropriate default values for each of the ring cadences.
This table only needs to be supported when the MTA
implements the E package. |
