## 1. Role

### JKKAdchgCancelHakkoSODCC.jdgOdr163()

This method generates **router-side connection information and modification Service Order Data (SOD)** for the "BBR not changed, ISP authentication ID changed" scenario (SOD issuance quality improvement initiative, 2013). It is invoked during the broader SOD issuance flow (`jdgOdr158`) when a subscriber's equipment provider contract (KKTSVKEI) exists and a valid device model/serial number can be identified, but the broadband router (BBR) itself has not been swapped.

The method implements a **conditional routing/dispatch pattern** based on the equipment provider service code:

- **BBR-only equipment (KKTK_SVC_CD_BBR = "C014")**: Issues an SOD with order content code `163` (router connection info change) via `tsuikabunAddSOD`.
- **Multi-function router (KKTK_SVC_CD_MFR = "C024") or Home Gateway (KKTK_SVC_CD_HGW = "C025")**: Queries the equipment operation service (KKOP) to check whether a router function is active on the equipment operation service contract. If found, it resolves the router's service contract number, performs a circuit inner-info confirmation via `runEKK0251A010`, and issues an SOD with order content code `404` (multi-function router setup/change - router function connection info change).

Before dispatching, the method validates that no DSL SOD has already been added for the same device (via `hasDslSodAdded`), returning early if a DSL cancellation/dissolution order already exists - this prevents duplicate or conflicting SODs. The method operates as a **shared utility** within the SOD issuance chain, called by the same-named method in `JKKAdchgHakkoSODCC` and `JKKHakkoSODCC` after equipment provider contract determination logic has populated the `sodMap` with the post-change equipment data.
