我正在尝试通过帧中继配置数据 T1。
ISP 向我提供了以下信息：
1. IP address
2. Gateway address
3. Encapsulation Frame Relay
4. DLCI 100
5. BZ8 ESF (I think the bz8 was supposed to be b8zs)
6. Time Slot (1 al 24).
到目前为止我所配置的内容如下：
interface Serial0/0
ip address <ip address> 255.255.255.252
encapsulation frame-relay
service-module t1 timeslots 1-24
frame-relay interface-dlci 100

对我来说一切似乎都已解释清楚，但显然我忽略了一些东西。
我的问题是我被困在接口启动、线路协议关闭的状态，所以 T1 无法启动。
答案1
你正在显示远程警报，你可能会发现思科故障排除指南有用。
假设硬件良好...
我会检查路由器和分界点之间的电缆，确保它已插入、未损坏、电缆没有损坏等。然后我会打电话给 ISP，询问他们为什么它不工作。上次我遇到这种情况是因为 AT&T 搞砸了，给了我错误的 DLCI，我花了六个小时的电话会议才弄清楚……
从您的更新中我了解到：
1725 input errors, 595 CRC, 1099 frame, 0 overrun, 0 ignored, 30 abort
经验丰富的人可能会有更好的想法，但这绝对让我怀疑你的布线有问题，或者线路噪音太大，或者电信公司的时钟完全错误。可能是时候召开电话会议了。
