关于在fedora 7下安装de210p的问题

我的安装环境是:fedora 7,asterisk 1.4.22,libpri 1.4.6,zaptel 1.4.11（以前有生产系统也是用此配置，只是卡是d110p),安装完成以后，启动平台报警告信息：WARNING[7552]: chan_dahdi.c:3784 handle_alarms: Detected alarm on channel 62: Red Alarm，卡上的红灯是间断闪烁红灯，请问这个是什么意思，需要怎么解决。
我的zaptel.conf配置为：
# Autogenerated by ./genzaptelconf -- do not hand edit
# Zaptel Configuration File
#
# This file is parsed by the Zaptel Configurator, ztcfg
#

# It must be in the module loading order

确认你的物理连接，可能物理连接有问题。

我用，指示灯就变成绿色了，但这个时候总是报：[Jul 1 15:05:31] WARNING[7646]: chan_dahdi.c:9517 pri_dchannel: PRI Error on span 0: We think we're the CPE, but they think they're the CPE too.
这个警告信息

你的是CPE 还是 NET啊，自己要搞清楚那个设置的。

signalling=pri_net
;signalling=pri_cpe

自环的时候，发什么就收什么，两边肯定要么是net，要么是cpe,有这个警告很正常
