Frequently Asked Questions

Q1. What Type of Channelized T1 signaling does Lucent support?
A1. Lucent supports three types of Channelized T1 signaling as follows:

E&M Wink Start

E&M Immediate Start

Foreign Exchange Station (FXS) Loop Start

Q2. Does the Lucent PortMaster3(TM)) support ground start circuits?
A2. No.

Q3. Does the PM3 support pulse dialing?
A3. No, the PM3 supports Dual Tone Multi-Frequency (DTMF). DTMT also is referred to as Touch Tone Dialing.

A4. The PM3 supports D4 or ESF framing and B8ZS or AMI encoding.

Q5. Does Lucent support ISDN connections over channelized T1 circuits?
A5. The PM3 will support 56K Voice-ISDN connections, V.120

Q6. Can Primary Rate Interface (PRI) and Channelized-T1 be configured on the same PM3?
A6. Yes, with a two T PM3 one line could be configured for PRI and the second line for channelized T1. The PRI must be connected to line0 due to clocking sensitivity. The PM3 clock source is external provided by the telco switch.

Q7. Does the PM3 support DNIS (Dial Network Information Services)?
A7. No, have the telco provider configure the circuit to send 0 digits for most switch types and 1 digit for DMS-10 switches

Q8. Do you have to set the ISDN switch type when configuring for channelized operation?
A8. No, ISDN switch type need not be configured for channelized operation. It is only required for PRI.

Q9. Can the PM3 be configured for FXO operation?
A9. No, please refer to question #1.

Q10. Will the PM3 accept less than 24 time slots (DSO's) per line as supplied by your telco?
Example 10 time slots.
A10. Yes, you can have as little as 1 time slot or up to 24 time slots per line. the total number of time slots for a two T PM3 is 48.

Q11. Can the time slots be configured for different signaling schemes supplied by the telco?
Example: Time slots 1 - 10 configured for FXS, Time slots 11 - 24
configured for Wink Start.
A11. No, the PM3 will only accept time slots configured for the same signaling.

Q12. Can the PM3 be trunk side terminated or line side terminated or both?
A12. The PM3 will support either trunk side termination or line side termination. Generally higher performance will be achieved if the PM3 is trunk side terminated.
