The Ameritech Region 5 Static IP packages are PPPoE. There are 4 packages that offer the 5 static IP addresses and all of the static packages have a -S appended to the name.
The Static IP Addresses are accessed via one PPPoE session.

The Router used has to be able to accept the subnet of IP addresses via the one PPPoE session and use them accordingly. Most of the less expensive Routers available will only do 1 to 1 NAT and access only one of the static IP's (the wan/gateway).

The username/user ID format changes for the -S packages, make sure you are logging in using the Master Account Member ID only to get the proper address blocks assigned:
yahootheclown@static.sbcglobal.net
yahootheclown@static_ameritech.net (legacy accounts)

The Compatible routers (i.e. 5861, 2-wire 1800, 3546) can perform multi-nat, and/or apply the public IP's directly to computers.

SBC/Ameritech bridges the subnet across 1 IP, your router takes up 1 IP, and there is the 1 broadcast IP, so in a class C range (which is what you get from SBC/Ameritech), you have 5 usable ip's (8-3=5)

The SBC/Ameritech Region is only offered a single 5 IP block unlike other SBC Regions which can order larger IP blocks.

This is an example of a SBC/Ameritech Routed Subnet with a total of 8 IP's 5 usable:

169.129.154.7 Broadcast (programmed in the RedBack, not useable by customer)
169.129.154.6 Router (WAN interface/Gateway)
169.129.154.5 Free for use on Lan(public/routable IP address)
169.129.154.4 Free for use on Lan(public/routable IP address)
169.129.154.3 Free for use on Lan(public/routable IP address)
169.129.154.2 Free for use on Lan(public/routable IP address)
169.129.154.1 Free for use on Lan(public/routable IP address)
169.129.154.0 Network (programmed in the RedBack, not useable by customer)

The usable Static/Public IP addresses are the 5 immediately below what your Router is assigned. The one before that and the one after the Router's IP complete the 8 IP block.

The WAN interface/Gateway is the only IP address that a Linksys, Netgear, SMC, D-Link Router would get/use. The last routable IP address is always assigned to the router.

An 8 IP subnet can also be called a /29 in regards to the Subnet Mask 255.255.255.248
The wan/gateway address is not in the same Subnet Mask as the /29 block 255.255.255.252

SBC/Ameritech will provide registration information for the IP address block
Your billing name and subnet block will be in a ARIN entry.

Existing users can upgrade to a static package with a $250.00 installation fee and the SBC supplied router/modem. It would be wise to check SBC's website for current pricing and/or equipment promotions, special conditions that apply to the -S packages.

There is no difference between a static and dynamic installation on the customer end except for the router and it's configuration. You can easily do that yourself. You don't even need their equipment as long as you know what you are doing.
On SBCIS's end, it's a RADIUS entry and a different Redback assignment, all done in software.
The installation charge for static accounts is a huge expense since the technician will configure the Router to NAT the static IP to the LAN, and use the Router's address as a gateway.

New users can sign up for a dynamic package and wait 2 to 3 weeks and "re-rate" to the desired -S package. This may be the best option because every copper loop is different and there is a significant price difference from dynamic to -S.

It would be wise to keep track of the remaining time of the term and call in and "re-rate" about 3 months prior to the 12th month of the contract. If you don't do this the billing may revert to the then current month to month pricing

Any info on ordering or re-rates are best handled by calling Team-Data or contacting one of the "SBC Official Techs" here on the BBR web site.
