T1_TRANSPARENT = 4
T1_TRANSPARENT – provides bearer
path termination (T1 system) without
signaling-related functions. Channels 1-
24 mapped to DSP channels. Used for
provisioning SS7 trunk or PRI trunk of
an NFAS group that does not host the D
channel i.e. B-channel span only.
E1_TRANSPARENT_31 = 5
E1_TRANSPARENT_31 – provides
bearer path termination (E1 system)
without signaling-related functions, with
reclaiming timeslot 16. Channels 1-31
mapped to DSP channels. Used for
provisioning SS7 trunk.
Note: If using E1_TRANSPARENT_31,
it is the only protocol type that can be
used on that board (or logical GW).
Note: There are 240 DSP resources per
logical GW. The first 240 channels
requesting a DSP resource have those
resources allocated. Attempt to open
bearer channels beyond that is denied.
E1_TRANSPARENT_30 = 6
E1_TRANSPARENT_30 – provides
bearer path termination (E1 system)
without signaling-related functions.
Channels 1-31, except 16 mapped to
DSP channels. Used for provisioning
SS7 trunk.
Note: Attempts to establish a bearer
path on timeslot 16 are rejected.

only over Brazilian, Korean and
Mexican R2 variants.
E1_CAS_R2 = 8
E1_CAS_R2 – this protocol type was
changed to E1_CAS. Megaco and
