Note:
For the analogue trunk interfaces the PN-8COTU card is available however with following
constraints:
The PN-8COTU supports TBR21, the investigations for TBR38 are still not finished.
Already is known that for Italy, Spain, South Africa, and Brazil the current PN-
8COTU requires adaptations. Implementations for these NSOs are scheduled for SW
R9.
As some country specific transmission plans do not match 100% with the PN-8COTU
supported transmission plan, voice and Modem/Fax signals to and from the PSTN
over the analogue trunk can be deformed.
For voice calls over the analogue trunk the audio/voice quality will be affected, echo
can occur or the user will hear a deformed audio/voice signal.
For Modem/Fax calls over the analogue trunk the mismatch causes data failures
resulting in low(er) modem/fax transfer speed rates.
As the PN-8COTU supports the SS/PD signaling, the Analogue Trunk will not be able to
detect a forward release. Therefore Direct Dial-In (DDI) is not supported on the PN-
8COTU.

? 4 circuit analog 2W/4W Tie Line card.
PZ-PW122 (-48V Power Supply) is required in case of
E&M Type-I signaling. Maximum of four SPN-4ODTA
per PIM, due to the power capacity of PZ-PW122.
This card is available from R8 (not available for R6.2).
PN-2ODTB is needed for R6.2.
