D110PG yellow alarm with zaptel 1.4.11

I was successfully using a D110PG with Asterisk and an older version of zaptel (1.4.7, I think) on a Fedora Core 5 system. After upgrading the system to Fedora 9 and installing zaptel-1.4.11 I cannot get the D110PG to give me anything other than a yellow alarm.

This is what 'dmesg' says:

Zapata Telephony Interface Registered on major 196
Zaptel Version: 1.4.11
Zaptel Echo Canceller: MG2
FALC version: 00000005
TE110P: Setting up global serial parameters for T1 FALC V2.1 or V2.2
Infineon PEF2256 V2.1 found
OpenVox D110PG V1 found.
TE110P: Successfully initialized serial bus for card

Registered tone zone 0 (United States / North America)
TE110P: Span configured for ESF/B8ZS
Calling startup (flags is 4099)
wcte1xxp: Setting yellow alarm

When I run zttool dmesg says this:

wcte1xxp: Clearing yellow alarm

However, in zttool it still says "YEL"...

Here is my /etc/zaptel.conf file:

span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
loadzone = us
defaultzone=us

I am using "wcte11xp_ARGS=t1e1override=0x00" in my /etc/sysconfig/zaptel file.

Thank you for your assistance on this.

It turned out to be a problem at the telco. (They had an internal loop on the circuit even though they had previously indicated that the circuit was status-normal.)
