PURPOSE: A bearer channel allocation and managing method of a medium and small capacity wire switch are provided to allocate and manage an AN-based bearer channel for processing a call using a V5.2 interface when a WLL subscriber requests an outgoing call or incoming call for thereby forming a communication path between a wire switch and a WLL subscriber and providing a PSTN cooperated service to a WLL subscriber of multiple AN. CONSTITUTION: A certain information is read from a database when initializing a system in a system library CSL(Call processing Shared Library), and an AN-based bearer channel information is formed based on a linked-list structure, and a point indicates a bearer channel information for transferring to a user block when a bearer channel allocation is requested(S2). An idle bearer channel is searched through a system library procedure defined when setting an outgoing call and incoming call, and a state information with respect to an idle bearer channel is changed an in-use state using a system library(S3). When a bearer channel receives a report that a service is not provided based on an operator's request or error from a resource management block, a bearer channel information is excluded from a linked-list structure(S4). When a service is available by a recovery, a bearer channel information is added(S5).
