现在的网络主管操心的事太多,必须考虑防火墙、认证、加密、压缩、分配有限的访问权限以及管理日益增加的远程客户,目前,随着更先进的远程访问盒的出现,网络主管就可以很有效的满足以上的各种要求。 网络服务公司可以将所有用户的拨号呼叫集成到一个Primary Rate Interface(PRI)的ISDN干线中,然后再将数据传送到企业的网络中。这样企业就可通过一个ISDN集中器取代所使用的modem架,同时还可节省大量的电话线。 这种PRI数字式连接除了可以支持56k modem和ISDN以外,还可以提供更高级的安全和管理功能。 理想的ISDN集中器可以将modem或者ISDN呼叫集中到T-1或者ISDN线路,并能支持
Nowadays, network managers worry about too much, and must consider firewalls, authentication, encryption, compression, distribution of limited access rights, and management of an ever-increasing number of remote clients. With the advent of more advanced remote access boxes, network supervisors can now Very effective to meet the above requirements. Network service companies can integrate all users’ dial-up calls into a Primary Rate Interface (PRI) ISDN trunk and then send the data to the corporate network. Such an enterprise can replace the modem shelf used by an ISDN concentrator, and can save a lot of telephone lines at the same time. In addition to supporting 56k modems and ISDN, this PRI digital connection provides more advanced security and management features. The Ideal ISDN Concentrator Centralizes Modems or ISDN Calls to T-1 or ISDN Lines and Supports
