DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 857 Remote Access 17 H12 NXDS0 Contiguous Specifies whether to hunt contiguous NXDS0 channels. This field only appears if y is entered in NXDS0. The hunt algorithm to satisfy an NXDS0 call is as follows: Remote Access The Remote Access screen is used to implement the Remote Access feature. Remote Access permits a caller located outside the system to access the system through the public or private network and then use the features and services of the system. Remote Access users can dial into the system using central office (CO), Foreign Exchange (FX), Wide Area Telecommunications trunks (WATS), and Integrated Services Digital Network Primary Rate Interface (ISDN-PRI) trunks. In addition, a dedicated Remote Access Direct Inward Dialing number can be provided. Valid entries Usage y/n Enter y to specify the ISDN information transfer rate for 1920 Kbps data, which includes 30 B-channels. When a PE is administered to support H12, the hunt algorithm to satisfy a call requiring 1920 Kbps of bandwidth uses a fixed allocation scheme. Valid entries Usage y/n Enter y to specify the NXDS0 multi-rate service. Valid entries Usage y Enter y to specify the “floating” scheme. NXDS0 calls are placed on a contiguous group of B-channels large enough to satisfy the requested bandwidth without constraint on the starting channel (no fixed starting point trunk). H0 and NXDS0 “floating” scheme cannot both be y. n Enter n to specify the “flexible” scheme. NXDS0 calls are placed on any set of B-channels on the same facility as long as the requested bandwidth is satisfied. There are no constraints, such as contiguity of B-channels or fixed starting points.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 858 Remote Access 17 !SECURITY ALERT: Lucent Technologies designed the Remote Access feature incorporated in this product that, when properly administered by the customer, enables the customer to minimize the ability of unauthorized persons to gain access to the network. It is the customer’s responsibility to take the appropriate steps to properly implement the features, evaluate and administer the various restriction levels, protect access codes and distribute them only to individuals who have been advised of the sensitive nature of the access information. Each authorized user should be instructed concerning the proper use and handling of access codes. In rare instances, unauthorized individuals make connections to the telecommunications network through use of remote access features. In such an event, applicable tariffs require the customer pay all network charges for traffic. Lucent Technologies cannot be responsible for such charges, and will not make any allowance or give any credit for charges that result from unauthorized access. To ensure the security of your system, consider the following: nMake all remote access facilities unlisted directory telephone numbers. nRequire users to enter a Barrier Code of at least seven random digits AND an Authorization Code of at least 13 random digits to make network calls. nMake Authorization Codes nonconsecutive (random) and change them, at least, quarterly. nDeactivate Authorization Codes immediately if the user leaves the company or changes assignments. nAssign the minimum level of calling permissions required to each Authorization Code. nBlock off-hours and weekend remote access calling, when possible. Use Alternative Facility Restriction Levels, if available. nUse a voice recording, warble tone, or no tone and avoid use of a dial tone as a prompt when the remote access unit answers. nAssign the lowest possible FRL to only allow internal switch calls. As an additional step to ensure System security, you can permanently disable the Remote Access feature if you do not intend to use it now or in the future. If you do decide to permanently disable the feature, it will require Lucent Services intervention to activate the feature again.

!CAUTION:
Your attempt to disable the Remote Access feature will be lost if the switch is
rebooted without saving translations. Therefore, execute a “save
translation” command after permanently disabling the Remote Access
feature.
To assist you in maintaining the security of your system, DEFINITY ECS
provides the status remote access command, which provides status and
information on each remote access barrier code and on the remote access feature.
A sample Status Remote Access screen follows the Remote Access screen.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 862 Remote Access 17 TN COS Assign the most restrictive class of service (COS), that provides only the level of service required to provide the maximum security. Expiration Date Assign an expiration date based on the expected length of time the barrier code will be needed. If it is expected the barrier code is to be used for a 2-week period, assign a date two weeks from the current date. If the Expiration Date is assigned, a warning message is displayed on the system copyright screen seven days prior to the expiration date. The system administer can modify the expiration date to extend the time interval if needed. No. of Calls The Expiration Date and No. of Calls fields can be used independently or in conjunction to provide the maximum security. If both the Expiration Date and No. of Calls fields are assigned, the corresponding barrier code expires when the first of these criteria is satisfied. Calls Used This display-only field shows the number of calls placed using the corresponding barrier code. This field is incremented each time a barrier code is successfully used to access the Remote Access feature. A usage that exceeds the expected rate indicates improper use. Valid entries Usage 1 to 20 (G3si) 1 to 100 (G3r)Enter the appropriate Tenant Partition number. Valid entries Usage 0 to 15Enter the COS number, associated with the barrier code, that defines access permissions for Call Processing features. Valid entries Usage A date greater than the current date Enter the date you want the barrier code to expire. Valid entries Usage 1 to 9999 Enter the number of Remote Access calls that can be placed using the associated barrier code.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 865 Route Pattern 17 RHNPA TABLE CODE Enter the desired 100-block, for example 000 through 099 or 900 through 999. A separate screen is required for each 100-block. Pattern Choices Code-Pattern Choice Assignments Route Pattern The Route Pattern screen defines the route patterns used by your switch. Each route pattern contains a list of trunk groups that can be used to route the call. The maximum number of route patterns and trunk groups allowed depends on the configuration and memory available in your system. Use this screen to insert or delete digits so AAR or ARS calls route over different trunk groups. You can convert an AAR number into an international number, and insert an area code in an AAR number to convert an on-network number to a public network number. Also, when a call directly accesses a local central office (CO), if the long-distance carrier provided by your CO is not available, your switch can insert the dial access code for an alternative carrier into the digit string. Valid entries Usage 1 to 32Enter the table number. You can use up to 8 screens for each table, one screen for each 100 numbers. Valid entries Usage Enter the route pattern number you want associated with each code. The pattern choice you list on one screen automatically defaults to the other screens of the same table. If you use one pattern for most of the codes, assign that pattern to choice 1. Valid entries Usage 1 through 12Enter a Pattern Choice number from the list above to choose the route pattern for each prefix code.
