Network Change:
AT&T Midwest will make changes necessary to support the Dial-With-Dial replacement of the Alcatel-Lucent 1AESS switch (CHCGILAUCG0) located in the Chicago-Austin central office, Chicago, IL, with a Nortel MG9000 remote switch (CHCGILAURP0) hosted from the Chicago Newcastle tandem switch (CHCGILNE20T/DS1).
Description of Type of Changes Planned:
The purpose of this Network Disclosure is to provide Dial-With-Dial information regarding the replacement of the Chicago-Austin, IL, 1AESS local switch (CHCGILAUCG0) with a Nortel MG9000 remote switch (CHCGILAURP0) hosted from the Chicago Newcastle tandem switch (CHCGILNE20T/DS1) during the second quarter of 2013.

Description of Reasonably Foreseeable Impact of the Planned Changes:
AT&T Midwest, Independent LECs, Wireless Service Providers, CLECs and Interexchange Carriers may be affected due to changes in routing of originating and terminating traffic associated with the replacement of the CHCGILAUCG0 1AESS switch. All interoffice trunking to CHCGILAUCG0 must be re-homed to the CHCGILNE20T/DS1 host switch. Direct Inward Dial (DID) and Primary Rate Interface (PRI) ISDN service will be served from the CHCGILAURP0 MG9000 switch. CLECs must evaluate whether their existing trunk groups to CHCGILNE20T/DS1 are adequately sized to support the addition of the CHCGILAURP0 traffic.
