This standard defines a recommended set of packet mode bearer service categories, describes individual packet mode bearer services,
21、 and recom- mends their provision as ISDN-based services in North America. The defi- nitions and descriptions in this standard form the basis for defining the net- work capabilities required for the support of ISDN-based packet mode bear- er services. Bearer service categories are described by prose
22、 definitions and descriptions, by attributes and their values, and by dynamic descrip- tions. The packet mode bearer service categories that are currently identi- fied are the virtual call and permanent virtual circuit bearer service catego- ry; the connectionless bearer service category; the user s
23、ignaling bearer service category; and the frame mode bearer service category. Only the vir- tual call and permanent virtual circuit bearer service category is included in this issue. Manufacturers of ISDN user terminals and manufacturers of ISDN switching equipment can apply this standard to the des
24、ign and development of their products. _This standard was developed by Working Group Tl Sl .l of Accredited Standards Committee Tl , Telecommunications. Many of TlSl .1s partici- pants are also active participants in similar activities of the CCITT. Therefore, this standard is consistent with CCITT
25、Recommendation 1.232 (1988). This standard contains one bibliographic annex.

45、 service category is included in this issue. NOTE - Frame Mode Bearer Services may also provide services similar to virtual call and per- manent virtual circuit. The other categories are for further study. This standard is based on CCITT Recommendation 1.232. The only technical dif- ferences between
46、 this standard and CCITT Recommendation 1.232 are that this standard mentions D channel congestion (see clause 1, paragraph 2) and this standard mentions per- manent virtual circuits on the D channel (see 3.1.3.1.2). 2 Normative references The following standards and publications con- tain provision
