I am replacing my current CSU/DSU and router with a CSU/DSU router combination to elimenate some equipment and save space. I have the replacement DSU/router combo ready to configure and I have called my ISP for the config info, however I am unable to decifer some of the info. I have all IP info but I believe I am missing some Serial settings. I was given the info below. Please me decifer the info and if I am missing something what else do I need? I am fairly new at configuring T1s but very comfortable with routing.
Serial IP Information:
WAN default Gateway (PAETEC): 199.xx.xx.113
Customer Serial IP: 199.xx.xx.114
Subnet Mask: 255.255.255.252
Public LAN Network:
xx.xx.xx.104/29 [1/0] via 199.xx.xx.114, Serial1/2/3/16:23.157
Subnet Mask: 255.255.255.248
Usable Public IPs:
xxx.xx.xx.105 to xxx.xx.xx.110
The IPs I understand but I do not understand the Serial1/2/3/16:23.157
meaning. Please help.
