Exhibit T

DIAL-UP INTERNET SERVICE SCHEDULE

Global Crossing acknowledges that Eschelon requests Global Crossing’s Dial-Up Internet Services.

Dial-Up Internet Service is a nationwide (U.S.A.) service provided by Global Crossing through a network that enables Eschelon’s End-Users that subscribe to Eschelon’s dial-up internet access product to access the internet.

Global Crossing shall (i) aggregate all incoming calls from Eschelon’s End-Users, (ii) convert data traffic to Transmission Control Protocol/Internet Protocol (“TCP/IP”) format, and (iii) route data traffic between the End-User and Eschelon or the Internet.

1.DEFINITIONS

Realm:  An identifier that links the user to its ISP. In many cases, this is done with the person’s login or email, like username@ispname.com where @ispname.com is the realm.

Available Dial-Up Markets:  Geographic areas in which Global Crossing Dial-up Internet Service is available as defined by the NPA-NXX availability list contained herein, which may be modified from time to time by Global Crossing.

In-Service Date:  The first date on which any of Eschelon’s End-Users use the Dial-Up Internet Services.

Dial-Up Network POP:  A Network Point of Presence, to which Available Dial-Up Markets are routed.

Home Market:  The Market in which an End-User has the greatest number of log-ins during the month.

Roaming Market:  All Markets in which an End-User logs-in during a month other than its Home Market.

2.Eschelon’s OBLIGATIONS

Prior to receiving the Dial-Up Internet Service, Eschelon shall be required to install the appropriate equipment in accordance with Global Crossing’s technical specifications and to complete a Set-Up Form, both of which will be provided to Eschelon by Global Crossing.

Acceptable Use Policy:

Eschelon shall maintain a written policy which is consistent with and includes all of the material terms of the policy http://www.GlobalCenter.net/aup, including without limitation, a prohibition against unlawful use of its network and requirement of cooperation with law enforcement officials in the pursuit of illegal uses of its network (such policy, “Acceptable Use Policy”). Eschelon shall require all of its End-Users to

3

adhere to such Acceptable Use Policy as a condition of receiving Global Crossing’s Dial-Up Internet Service. Failure of an End-User to comply with such Acceptable Use Policy shall be grounds for termination of End-User’s access to the Dial-Up Internet Services at Global Crossing’s request. Notwithstanding anything herein to the contrary, Global Crossing may block any data traffic to or from End-Users, which Global Crossing reasonably determines violates its Acceptable Use Policy. The Acceptable Use Policy is subject to change with notice by publication on this Web-Site and Eschelon is responsible for monitoring this Web-Site for changes.

Realms and Phone Numbers: Eschelon is required to use Realms and will share dial-in phone numbers with other customers of Global Crossing subscribing to the Dial-Up Internet Services. If Eschelon wishes to provide toll free access to its End-Users, Eschelon can subscribe to that Service from Global Crossing in accordance with Global Crossing’s terms and conditions for such toll free access Service. Eschelon may request access numbers in all available markets permitting seamless roaming by End-Users.

Monthly Capacity Forecast: Eschelon is required to submit monthly capacity forecasting by Dial-Up Market by the first (1^st) calendar day of each month. Forecasting reports shall contain a rolling six-month projection from the date submitted for each Dial-Up Market. The initial markets to be activated, along with the initial six month rolling End-User forecast for each is required prior to Service activation. In the event Eschelon fails to submit a forecast in accordance with this provision, then Eschelon shall have waived its right to receive any credit for the affected month as stipulated in Section 7 hereunder.

3.TERM

Eschelon agrees to purchase the Dial-Up Internet Service for a term of Two (2) Years from the In-Service Date (the “Dial Up Internet Initial Term”). Unless a party has given the other at least 90 days prior written notice of its intent to terminate the Dial Up Internet Service upon expiration of the Dial Up Internet Initial Term, the Dial Up Internet Service renews automatically for one year terms at the expiration of the Initial Term until canceled by either party upon at least 90 days prior written notice.

In the event the parties do not agree to remain in the Dial Up Internet Service and Eschelon elects to migrate End-Users off of the Dial-Up Network (the “Migration Date”) the terms and conditions of this Dial Up Internet Service shall remain in effect for 4 months following the Migration Date and the number of End-Users to be migrated per month shall not exceed *** of the total number of Eschelon’s End-Users on the network as of the Migration Date.

During the Dial Up Internet Initial Term, should Global crossing make any changes in the network which result in Global Crossing being unable to provide the Dial-Up Internet Service in compliance with this schedule, Global Crossing will provide at least ninety (90) days prior notice to Eschelon and will at Eschelon’s request, work with Eschelon on a plan mutually agreed upon in order to assist Eschelon in migrating its end-users to another provider of Dial-Up Internet Service of the type and service level being provided, or substantially similar to that being provided by Global Crossing hereunder.

4.RATES AND CHARGES

(a)End User Count (EUC). For billing purposes Global Crossing shall treat each log in as a unique End User and shall be counted as one End User regardless of the number of times logged in or End User location. Additionally, if an End User logs in two or more times simultaneously to the network with the same user name, Global Crossing shall treat each log-in as a unique End-User.

(b)User Fee. Each month Eschelon shall pay Global Crossing a “User Fee.” The total User Fee will consist of two components:

(i)Pre-Bill Amount (estimated usage): The Pre-Bill Amount for the current month shall be equal to the greater of (a) the Minimum EUC times the Fee Per End-User; or (b) *** of Eschelon’s actual EUC from the previous month as indicated on Eschelon’s current months Invoice times the Fee Per End User.

(ii)Reconciliation Amount: If and only if the actual usage during the previous Month was in excess of the Pre-Bill Amount from the previous month’s Invoice then the Reconciliation Amount is calculated by the following formula: previous month’s actual EUC times the previous months rate minus previous month’s Pre Bill Amount.

Pricing Tier	BILLABLE LOGINS (Minimum EUC)	FEE PER END USER
***		***
Tier One	***	***
Tier Two	***	***
Tier Three	***	***
Tier Four	***	***

(c)Minimum EUC: Fifteen (15) days prior to the end of the Ramp Up Period, Eschelon is required to submit to Global Crossing in written format in accordance to Section 4(d) below, Eschelon’s initial minimum end user count commitment level according to the above pricing table (the “Minimum EUC”). The Minimum EUC commitment shall commence with Eschelon’s first full Billing Cycle following the Ramp Up Period and shall continue in effect until modified in accordance to Section 4(d) below.

5

(d)Commitment Notice: (i) Eschelon’s initial Minimum EUC must be submitted to Global Crossing fifteen (15) days prior to the end of the Ramp Up Period via the Commitment Notice to the attention of Contract Administration; and (ii) At any time during the term of the Dial Up Internet Service, Eschelon may provide Global Crossing with written notification of Eschelon’s intent to increase the Minimum EUC in order to qualify for a lower Fee Per End User (the “Commitment Notice”). Such new Minimum EUC shall be provided to Eschelon via the Commitment Notice (sample attached hereto) with the new Fee Per End User rate being effective in the next full Billing Cycle following the execution date by Global Crossing of such Commitment Notice.

(e)Excess Usage Surcharge: In the event Eschelon’s average Dial Up Internet usage per End-User, calculated across Eschelon’s entire user base, exceeds *** hours per month, Eschelon shall pay a surcharge equal to *** multiplied by the total User Fee for each hour in excess of the *** hours average per month (rounded up to the nearest tenth of an hour).

(f)Setup Fee: Eschelon shall initially be assessed a monthly “Setup Fee” equal to *** per new End User and shall continue to be assessed the Setup Fee for each new End User by taking the difference between Eschelon’s current month’s EUC and Eschelon’s previous highest month’s EUC.

(g)Realm Fees: The first two Realms are supported at no charge. The fee for each additional Realm shall be ***. The fee for changing a Realm shall be ***.

(h)Toll Free Registration Fee: A one time set-up fee of *** for each Toll Free number provisioned will be assessed to Eschelon’s account with a usage fee for such Toll Free service of *** per minute, rounded up to the next six second increment.

(i)Fee Adjustment: During the Initial Term for the Dial Up Internet Service, Global Crossing shall not increase the fees or charges set forth herein, unless there is a substantial increase in the cost to Global Crossing of providing the Dial-Up Internet Service. In such event the increase shall be limited to the amount necessary to cover those costs. Global Crossing shall provide at least thirty (30) days advance written notice to Eschelon of such increase.

(j)Global Crossing reserves the right, at any time and at its sole discretion to terminate this Dial Up Service for Eschelon’s under-utilization of such Service. Such under-utilization is defined as an EUC less than *** per month.

5.INVOICING

Eschelon shall be Invoiced for the Dial-Up Internet Services on a monthly basis. For the purposes of the Dial-Up Internet Service, a “Month” shall mean the period beginning at 12:00:00 a.m., Local Time, on the first day of each calendar month and ending at 11:59:59 p.m., Local Time, on the last day of each calendar month. “Local Time” refers to the time in each time zone where a given Dial-Up network POP is located. Any calls that begin in one Month and conclude in the following Month shall be invoiced to the later month.

6.VOLUME AND CAPACITY LIMITATIONS; NUMBER PORTABILITY

(a)In order to ensure that capacity spikes from individual customers do not adversely affect all other customers, Global Crossing requires Eschelon and all other of Global Crossing’s customers to abide by capacity increase guidelines. Commencing with the first full Billing Cycle following the Ramp Up Period, Eschelon is allowed to increase its usage by *** per month per Dial-Up Market without prior written approval from Global Crossing. If Eschelon wishes to exceed this threshold Eschelon shall request approval from Global Crossing through submission of the monthly forecast at least sixty (60) days prior. Global Crossing will respond within 15 days if capacity is not available to permit the excess usage. However, Eschelon may increase its usage by up to *** per month per Dial-Up Market beyond its submitted and approved forecasts. If Eschelon’s incremental usage exceeds the allowable capacity increase after receiving notification that capacity is not available or without providing notice in the monthly forecast, Eschelon will be notified and Eschelon shall have waived its right to receive any credits under Section 7 below for the months in which Eschelon’s incremental usage exceeds the allowable capacity increase. If there is no available capacity some users may receive an authentication error when attempting to log in.

(b)Commencing with the first full Billing Cycle following the Ramp Up Period, if Eschelon has not provided a forecast for a roaming market and in a given month its logins in that market exceed *** of its total logins in all markets combined, then Eschelon shall have waived its right to receive any credits under Section 7 below for that month. If there is no available capacity some users may receive an authentication error when attempting to log in.

(c)Capacity Decrease Guidelines: Commencing with the first full Billing Cycle following the Ramp Up Period, if Eschelon’s End-User usage decreases by more than *** from the previous month, then Eschelon will be billed at a usage level that is equivalent to *** of the previous month’s usage.

7

(d)Number Portability: Notwithstanding the availability of number portability in a particular jurisdiction, the Parties agree that any line numbers assigned to Eschelon in connection with the Dial-Up Internet Service are provided solely for the use of Global Crossing Services. Following termination of this Dial Up Internet Service and expiration of the Migration Date under Section 3 above, Eschelon shall be prohibited from using or porting any line numbers assigned to it by Global Crossing.

(e)Except as otherwise provided herein, Global Crossing does not warrant interruption free Dial Up Internet Service and disclaims all warranties, express or implied, with respect to the Dial-Up Internet Services, including without limitation the warranties of merchantability and fitness for a particular purpose.

7.SERVICE LEVEL AGREEMENT AND CREDITS

Global Crossing measures the performance of its Dial-Up Internet Service in four categories. In the event Global Crossing’s network performance in any given month, as measured against Visual Networks’ data for the month in question, is below any of the four measurements as detailed below, then upon Eschelon’s written request for any credit within 30 days (such credit request shall include sufficient documentation detailing the failure), Global Crossing shall provide a credit in an amount equal to *** of the End User Fee for each category which is below the applicable months Visual Network’s measurement. Such credit shall not exceed four percent *** in any given month. Global Crossing at its sole discretion reserves the right to modify the measurement percentages, if Visual Networks materially changes its testing methodology.

(a) 24-Hour Call Success Rate - 95%

(b) Busy-free Dial - 98%

(c) Initial Modem Connect Speed - 46 Kbps

(d) Average Web Throughput - 4.2 KBps
