Good morning!
Qwest started offering ISDN in our area recently. We have ordered one PRI
to test the service out. I'm having a heck of a time getting it up and
running, however. I get the DSP ALM light on, and depending on my NFAS
settings (see below) I may get the LPBK/D-ALM light on.
Qwest is using a Lucent 5E switch here. I'm using a single-span hiper DSP
with 3.5.105 firmware.
For my trunk settings, I have the following:
Framing Mode dsx1ESF
Line Coding Options dsx1B8ZS
Circuit Identifier
Loopback Configuration dsx1NoLoop
Signal Mode messageOriented
Transmit Clock Source loopTiming
NIC Type longHaul
Response to Remote Loopback respond
Jitter Attenuation attenJitterOnRcvr
Transmit Line Build Out dB0pt0
Dial In Address dnis
Dial In/Out Trunk Start Signal Type wink
Ack Wink On Dial In Address Info Received disabled
Dial Out Address Delay 70
Dial In/Out Trunk Type eAndMTypeII
Primary Switch Type priSwNI2 (SAME RESULTS WITH priSw5ESS)
Idle Byte Pattern 254
Receiver Gain dB26
Tone Type dtmf
Number of DTMF Tones 4
Send Code dsx1SendNoCode
External Signaling Mode (will take effect next boot) none
Overlap Receiving Mode disable
Overlap Receiving Inbound Digits Expected 12
Overlap Receiving Timeout Delay 12
For NFAS settings, I have:
NFAS Interface ID 0
Logical Group Number 0
NFAS Span D-Channel Type dChannelNone
Logical Group Type nfas
If I change NFAS Span D-Channel Type to dChannelPrimary (the default) I get
the red light on LPBK/D-CHAN
The Qwest tester hasn't been much help with the settings, I'm wondering if
anyone else knows what the "standard" settings should be. Thanks in advance
for any clues.
