DSP Island (DSPI) Resource Provisioning
Note: Each DSP RM provides a total of 9 DSP Islands (DSPIs).
The resources should be allocated across the RMs so that
the DSP messaging load is evenly distributed. Only one
type of resource can be provisioned per DSPI. The follow-
ing table defines the capacity number for each resource:

Each of the values in this capacity column is equal to one DSPI.

Notes and Descriptions
COT 80 COT = Continuity tone transceiver.
Tone-
Syn
255
It is not recommended
to have more than 14 ABBIT
resources (one ABBIT DSPI) on an RM that also has
255 ToneSyn (Tone Synthesizers) resources allo-
cated on it, since both of these resources are mes-
saging intensive.
DTMF 64 DTMF = DigiTone/Multi-Frequency receiver with dial
ABBIT 14
It is not recommended
to have more than 28 ABBIT
(AB Bit) resources (two ABBIT DSPIs) on the same
RM.
MF 40 MF = Multi-Frequency receiver
Note: Each SPM CEM card has 4 DS512 ports which are cabled
via fiber straight from the front of the CEM cards to ENET planes
using NT9X40DA Paddleboards; then from the ENET via existing
DS512 fibers to the MS.
